@DRM1-- why do I have three tablets?
Well, I use one at home, which also goes with me on the road. I log into the office with RDP.
I have three at the office -- one for me, one for my partner, and one is a spare, because now and then something doesn't work somewhere.
The nurses use X200 (not tablet) for portability -- we have several of those. I get them on E-bay, and I have never had a problem with them not working. They seem bullet proof.
I bought the x220T new, and I have 3 x200T's. I actually prefer the older machines, but it's pretty much of a toss-up. The X220T has a faster processor, and works marginally better with Dragon.
