robrahm, I am not a student but will offer a couple of commments. I think the trade off is about size vs portability. The 12 inch display gives something roughly the size of a sheet of paper. There are several TPC's with even smaller screens that still have their popularity. The bigger you go the heavier you get. I have a Motion M1400 VA and love it. The VA helps also with fluorescent lighting glare. The M1400 screen has a very wide viewing angle which is a separate thing than the View Anywhere feature. (that was the problem with the TPC you refer to above). That does help a lot if you will be having others look on with you any (some have even mentioned liking the older models for privacy concerns because they are hard to see from the side, such as when doing business work on a plane).
