My laptop has been acting up, so I bit the bullet and purchased a Toshiba Portage tablet PC (M200) this week. If you are in the market for a Tablet, I highly recommend the Tablet from Toshiba. First off, Toshiba's tablet is the only Tablet with SXGA res that I know of 1024x768 just doesn't cut it for me. Second, it is one of the few that supports 2GB of Ram (Most top out at 1 GB). And third, it is the only one that comes with a nice nVidia GeForce FX card. On the downside, it doesn't come with a cd/dvd, so you will have to drop a few hundred bucks on a USB powered one.
It you do get a tablet, make sure to get the Dictionary Power Toy so that you can add new words to the dictionary as you run into them (mainly company names so far). Because the Tablet really sucks at converting Ink when the word you are spelling is not in the dictionary.
