If those are some of the older Gateways, they used a different technology other than Wacom, which is used in all of the other tablets. I think they were trying to save a few dollars. They do work, but not as well as others. I ran across those when I was doing some retail training for Intel with processor platform education and they were not my favorites and some were what I called the "monster" tablets...big and too bulky to carry around.
With the last name of "Duck", yes I get a lot of jokes and thus I am not very thin skinned (grin). I tell just about as many as I hear so the name Medical Quack seemed to fit for the blog.
I address things from the programming side of things and no longer write, but a few years ago I wrote an EMR, which for it's time was good, but with recent changes, you can't have a life and do the same, it takes a team of at least 2 or more by today's standards.
My best advice with using tablets it to take some time to get to know how to use one and play around with Windows Journal a bit, which comes with every tablet and that way when you start to use a tablet with medical records, it will make a little more sense as humans we are not quite instant plug and play yet (grin).
I wrote an article too about the plight of the EMR vendor a while back and it floated around the web quite a bit, basically telling the story on the other side of the hard work that EMR vendors put in to creating software, thus going back to the teamwork concept of both sides working together and the next level of genomics coming down the tubes and where do we go with the next level there. Again feel free to email me at any time and I'll do my best to answer any tablet questions as well. I am a Microsoft Partner and can offer a lot of assistance too with MS Office too. Anyway, here's a link to the post for anyone who might want to take a look.
