I'm fully aware of what a pressure-sensitive screen is, if that comment was for me
. I merely summed up my experience for you based on what I gathered from your earlier posts; i.e., you didn't want a pressure sensitive screen a la PDA device and wanted something you could draw on without any issues. There are several different varieties of Tablets available, though the slates tend to lend themselves better for art usage; unless you want to lug around the extra weight of a larger battery or the keyboard. While the Compaq TC1000 does use an active digitizer pen, it didn't support various pressure levels, though the TC1100 may have. Some even have digital erasers built-in, so you can flip the pen over and erase any errors that you made.
The OQO I have now, while it has a built-in Wacom digitizer, is too small for any practical drawing applications, unless you like doodling on large Post-It notes! Not to mention the screen is of the variety I mentioned in my earlier posts; i.e., it doesn't have a hard piece of plastic stuck over it so it always feels as if you might accidentally smash it in if you press too hard.
Good luck on your search!
