The "Up-Side" to Refurbished Ultrasound

We all have our preferences for pretty much everything in life. It's rare that we like two things the exact same amount. However, there are differing degrees of preference which are frequently related to the price tag. If I'm planning on grabbing a burger with my wife, it's not really a big deal where we go. I would prefer one restaurant's burgers over another's, but I'm not going to be particularly concerned about it. Now if I'm taking her to an up-scale restaurant for a delicious steak, I'm planning on dropping a few bucks on the meal so I'm going to be more selective.
Take cars for example. If I need a good, reliable 4-door sedan, there's no shortage of those on the market. How much difference is there between a Camry, Fusion, 200, etc.? Sure, there's certain things that I like about each. If I think I'd prefer a new Fusion because I love the audio system with mySync, then I run across a Camry that looks brand new, low miles, great color, leather, etc. and it saves me thousands of dollars, I'd be happy with it. But if I hit the jackpot on the lotto and I'm heading out to buy my new Ferrari, I know exactly what I want and the Jaguar isn't going to cut it no matter how much it saves me.
And so it is with ultrasound systems. If I'm looking for a good, reliable ultrasound system that gets great images and has everything I need for my new mobile ultrasound business, I'm going to shop around and look for where I'll get the most bang for my buck. (Shameless plug: I'd go with a Terason uSmart 3300, great value, great warranty, great images) And typically the name brand is important, but my value-per-dollar is the key point. I know the systems I'd avoid because of reliability or "build quality" issues, but otherwise, there's a good selection available.
If I'm looking for a full-size cart based system for my echo lab or cardiologist's office that won't be going mobile, I'm likely to choose a system with which I'm very familiar. I have a long history with the Philips iE-33, as well as some Toshiba systems and the GE Vivid e9.
My mom used to tell me that it's difficult to have champagne taste when you're living on a beer budget. So I set out to figure out a way to do just that: get people what they want without breaking the bank.
Before I go on, let me first explain that any dollar amounts I throw out are based on my experiences as an applications specialist for Toshiba, as a clinical education specialist for Philips, and as a sales manager for United Medical Instruments, Inc. I try to be as accurate as possible, but everyone knows - prices are always subject to change.
My main question is this: if we are so willing to purchase a used car to avoid the huge drop in value as soon as it leaves the lot, why don't we accept that for ultrasound systems? I'll tell you why: a new Philips iE33 is very pricey, but it comes with some very important features. Warrant, service contracts, installation training, and advanced courses depending on the configuration.
Look at refurbished and used systems. Just give it a shot. Window shopping doesn't cost a penny. Be aware that you will likely run across some "fly-by-night" dealers out there, but they're the exception, not the norm. You could call me and say "Hey, Eric, I really really really want an iE33 with 3D, but they're so expensive new, and if I get a used one, I won't get the training I need!" Well do I have a solution for you! Get your champagne taste buds ready, because a bottle of Dom is coming your way.
Not only does UMI offer extended service contracts, but we offer installation training as well. It doesn't stop there, though. After my years with Philips, I learned what my customers wanted in their off-site (go to a training center) courses and I have developed courses to follow suit with the OEM courses. This allows you to purchase the system with the confidence that you'll end up being able to use it at least as well as you would by being taught by the OEM instructors. This training is offered by my company National CME and can be combined with your ultrasound purchase.
So the high-level CME courses related to 3D echocardiography get the cardiac sonographer all excited and the taste buds begin to tingle. Then they remember their budget. The 3D course taught by National CME (www.nationalcme.org) goes over everything the Philips team teaches about 3D echo on the iE33 and more. We left out the 3 hours of connectivity lectures that your IT people need rather than you and replaced it with other information including revenue information and case studies.
Their list price to just attend the course, no travel or accommodations included, is over $10,000. That is not a typo. Our course tuition list price is $1,495. We also offer on-site training at a MAJOR discount over OEM pricing. Our last on-site training special was 94% less than the equivalent training by Philips. And here's the great part: since I was recently a Philips employee, I have the exact same training as them all the way up to the latest iE33 V2012 software including 3D and speckle tracking technologies!
So the whole point of my story is that if you're looking for a full-size cart based ultrasound system, don't feel like you're stuck buying brand new because you might not get the training or service you need. You can get all of that right here. Just send me a message and I'll get you more information.
And one last thing: if you have a system that you need training on, National CME can train you even if you didn't purchase from me!
Have a great week, everyone. And have a great time shopping for your new or used systems!

About Core-M and the MacBook


I was investigating a little bit more about one of the key elements of the MacBookshowcased as part of the Apple Spring Event. I love the industrial design (and Jon Ive's voice, by the way) and the technology deployed in this new laptop. The motherboard is amazingly small, and this is so because Apple has been able to remove the fan system, plus use state of the art technologies.
This was one of the "wow" moments of the presentation. But this is when technology arises to help us to put this in perspective.
First, look at this benchmark results:
These are Geekbench 3 results from a Core-M CPU and an iPhone 6 Plus. Now, imagine how small is the motherboard of the iPhone 6 Plus. Yes, the iPhone 6 Plus is1 GB RAM, and MacBook is an 8 GB RAM system. But storage wise, the iPhone 6 Plus has 128 GB, plus WiFi 802.11ac, cámeraUSB/Lightning, audio and even theM7 coprocessor plus the Biometric one.
The real innovation is just here and is the smartphone. CPU ARM architectureimproves at a fastest pace than x86 architecture and the performance of ARM SoCs is getting better with each iteration.

The 5 Watts dilemma

In the MacBook presentation, they claimed that the TDP of the Core-M was just 5 Watts.
But "standard" specs of Broadwell-Y processors are 4.5W. The key point here is to maximize the performance at all costs (1.299$). The Core-M is placed in the lower side of the printed circuit board, probably to be in touch with the aluminium enclosure. This clever topology should be the secret sauce for this extra 0,5W of performance. It seems quite insignificant, but 0,5W out of 4,5W is a 9% extra roomfor MegaHertzs. And 9% is worth the effort when we are running out of performance.
The result is that the Core-M CPU doesn't fit in any spec sheet available in the ARK portal where Intel collects the technical specs of its processors and chipsets.
AnandTech pointed out they were the 5Y70 and 5Y71, but I guess they are the Core-M 5Y31 with the TDP UP frequency set up to 1,1 GHz, the Core-M 5Y51 up to 1,2 GHzand for the fastest one, the Core-M 5Y71 up to 1,3 GHz.
The point is: why Apple didn't choose to usethe official TDP UP parameter and stayed0,1 GHz below for two of the three available CPU options?
You can argue that 0,1 GHz is not big deal. But look at the three available CPU options: they differentiate in steps of 0,1 GHz. And while other manufacturers stick to the Core-M 5Y70 without TDP UP options (and guess a lower price point below the flat 281$ figure) Apple has put a lot of resources tweaking the CPU to get all the extra juice available. And this requires an exponentially increasing amount of design resources to accommodate the thermals of this x86 processors from Intel.

Live test experience

This laptop is, by all means, the pinnacle of laptops. Unfortunately I'm not optimistic about performance neither autonomy. Watts are directly related to performance. And you have to manage just 5 Watts for CPU and graphics. And add the thermal variable to the mix. Keeping the laptop on you lap should be an issue if that interferes with the dissipation of the heat. Not a thermal issue, but a performance one. If the CPU clocks down to keep things cool, the performance will be clocked down as well.
This is just a theoretical analysis, of course. Live experiences are key to fully disclose the behaviour of a system as unique and complex as this MacBook. And to disclose the behaviour of Intel x86 architecture when dealing with low everything: as low as500 MHz clocks and less than 0,7 Volts. 

Architecture convergence

As we saw before, synthetic benchmarks as Geekbench 3 show a similar performance for Core-M and Apple A8 processors. There are differences beyond synthetic benchmarks, of course, but raw performance starts to converge.
ARM and x86 meet in the low power arena. And here is where x86 needs to improve a lot. ARM scales up (apparently) with more dignity than x86 scales down.Intel should be better reinventing x86 with Skylake.

Oh No! My MacBook Air is out of memory!

The MacBook Air is a great computer due to it’s slim form factor (it’s thin!) and it’s super light weight. The current 13″ model weighs in at just under 3lbs. What a great little computer. The only issue is the small hard drive. It’s so easy to buy a machine with only 128GB of hard drive space and use it up within a month. So what do you do? Virtua Computers has the answer.
If you have a 13″ MacBook Air, or an 11″ MacBook Air – you can get the OWC Aura drive. With a 480GB and a 1TB model, for the 2013-current model, this tiny chip board holds a punch! OWC provides you the tools to make the switch from your old hard drive to the new one. . We actually just installed five of these drives in MacBook Airs that came with the wrong hard drive. The swap is easy. Open the bottom of your MacBook Air, unscrew the hard drive, put the new one in and close it up. That’s it! With the enclosure from OWC that you can put your old hard drive into, it’s an super easy way to transfer your files to your knew enhanced, larger drive. In our testing we have found the OWC drives to be faster than the stock hard drives from Apple.
Not feeling comfortable opening up your computer? Have no fear. You can pick up a Nifty drive for any computer that has a SD card slot (sorry 11″ MacBook Air). The Nifty drive will actually hold a MicroSD card and slip into the SD slot. The result will be a flush, clean look and a second drive on your computer.. Using the Nifty, you can set up a time machine drive to backup your data if you wanted to. It’s a great little solution for people on the go. While a 512GB micro SD card will set you back a few dollars, this is a great way to increase storage without opening your computer.
Need help getting these new hard drives up and running? Contact Virtua Computers for help!

Analyzing Big Data on Macbook?


I just received a new ultra-portable MacBook 2015.  I primarily use it for email and word processing but have also been testing it out using SAS running locally on the laptop.  SAS currently does not have a native Mac OS version so I am running it inside a Windows Virtual Machine (VM) using Parallels.  There have been many reviews criticizing how under powered the new MacBook is due to its Intel Core M processor.  I initially thought that running a Windows App through a VM such as SAS that normally brings servers to its knees would not work.  To my surprise, it worked quite well.  
Besides being able to work interactively with SAS, I was curious how it would perform running multiple SAS jobs analyzing data in batch mode.  I needed hard numbers to compare so I ran some benchmark tests in comparison with a server with 8 CPUs and 30GB of RAM as compared to this little laptop with 1 CPU and 1GB of RAM.  The MacBook actually has dual core CPU and 8GB of RAM, but the VM only allocated 1GB for Windows and SAS.  This does not seem fair and is not an "apple to apple" :) comparison.   The result which I show in this video was surprising in that the MacBook outperformed the server in several cases.  In general, it performs faster when running a single program at a time.  I even performed well when submitting two SAS jobs at once.  However, it started to lag behind the server when submitting five jobs simultaneously.
SAS does utilize CPU to perform analysis but it is also very I/O intensive.  My theory for this is that the new MacBook utilizes a new PCIe bus for its SSD drives which boosts I/O performance against traditional hard drives with SATA bus on most servers.  There may be many other factors such as other users on the server and which SAS PROC you use, but this test does show how you can perform powerful analytics even when on an airplane disconnected from server farms while using the new ultra-portable MacBook.

Why I Chose a Macbook Pro

As a developer the struggle of choosing a new laptop today is not an easy task, it requires hours upon hours of research followed by comparisons and benchmarks of CPU's and GPU's. I was coming from a Lenovo all in one pc with 4GB of ram and a low end integrated graphics card so this should've been easy right? .. Wrong. Many things come into consideration when buying a new laptop, battery life, weight, screen size, thickness and resolution. I found that I could buy a kick ass gaming laptop for $2000 - 2500 with much better specs than a mac for the same price. Although what the gaming laptops lacked in was everything a Macbook Pro has going for it.
Asus ROG-751 makes an amazing gaming laptop that comes with 24 GB of ram and expandable to 32GB, 4GB dedicated memory using a Nvidia GTX 980M, a processor with great turbo boost clock speed of up to 3.7 Ghz. All of that power under the hood for $2400, rated the best gaming laptop to have in 2015 by various different sites.

The Flip side 

The Asus ROG-751 was rated one of the highest due to it's battery life and not making and excessive amount of noise while doing strenuous tasks or basic tasks like web browsing etc.
Battery Life
  • Average life is 4 hours
That means in a 8 hour shift a user would have to fully charge his/her laptop batterytwice to be able to continue working.
Weight
  • 8.4 lbs
It's not something I would want to keep lugging around all day long, and no matter where you go you'll need to bring the charger with you making it a 10lb baggage.
Screen Resolution
  • 1920 x 1080
HD but for the price it's a low end resolution screen, having a crisp clearer image is ideal for anyone buying a high end piece of technology.

How Bout Them Apples?




After looking at Macbook pro specs vs Windows based gaming laptop I started thinking, why would I ever buy a Mac if I can get more performance per dollar I spend on a Windows. Well performance is a big factor but it isn't everything..I don't see track stars running with high performance shoes without shoe laces, the strings that brings it all together and make it a complete package!
Battery Life
  • Average life time is 10 hours
After having bought the laptop I was shocked at how long the battery lasted and how I could leave my house comfortably without the fear of running out of juice.
Weight 
  • 4.5 lbs
Practically half of any high end gaming laptop and half of the thickness as well coming in at 3/4 of an inch.
Screen Resolution
  • 2880 x 1800
Starting a Macbook Pro for the first time looking at Yosemite national park background with such a high res was amazing, the crisp detail on such a large image is great.

Conclusion

Coming from a user who has never even touched a mac and always used windows as his environment the transition was easy and there is minimal downtime for getting accustomed to a Mac and it's unique way. The mac experience is refreshing and doesn't just give you a computer it's just the all around package which is the biggest selling point.  
The battery life was one of the major factors in my decision, the reason for having a laptop is to have that portability and not feel chained down to a certain location because of power requirements and I felt like gaming laptops held up their end in terms of high end performance graphically but lacks enormously on the longevity aspect.
Weight was also concerning to me because I didn't want to carry something that wouldn't feel comfortable. MBP is so light that it almost feels natural or as if your not carrying anything at all which is a big selling point for a user who likes to move around in whatever workspace he/she is in.
Overall I think I made the best decision because I took the other key factors into play vs just looking at hardware specs instead of the overall experience. ROG make great laptops that can outperform Macbook Pros but a Macbook pro will be running 2.2X longer, weigh half and have almost twice the pixels per square inch with retina display.
