The Toshiba is definitely the Powerhouse of all the TabletPCs, but only because of its Geforce graphics and upgradeable to 1.6GHz Processor, which doesn't make a difference unless you play games. I would definitely suggest the Electrovaya Scribbler over the Toshiba, though, because of size and weight. The Toshiba has an SXGA screen, the only one that has that high a resolution screen. All the others are just 1280x1024, but that's always been enough for me, and I used to crank my desktop systems to 2048x1962. Scribbler in slate mode (it also comes with a detachable keyboard) is light, smart, and smooth. It's my Tablet of choice. Plus the Electrovaya screen is incredibly bright. ... and 8 HOURS of battery life, with WIFI on. It really last that long, that's not just an absurd speculation. It will last you a full day on one battery charge.
Screen protectors are a waste of money. I've had my Motion M1300 for two years now, and I use it every day in all of my classes. These things just don't get scratches.
Also, if the Electrovaya doesn't tickle your fancy, take a look at HP's new TabletPC that they just released last month. It's nearly as good as the Toshiba M200.
