My vote is the Motion 1400. I have had it for several months. I researched tablets fairly extensively prior to my purchase, and I have really loved it!
Features that motivated my purchase:
- view anywhere screen, which is great
- a larger display
- integrated 802.11b/g WiFi, Bluetooth and Fingerprint Reader
-good ergonomics/lightweight
-ample RAM and large hardrive. Centrino. It is FAST.
-3-4 hours of battery life
-ariplane/car adapter available, which works great
-convertible cover keyboard available, as well as bluetooth
-very nice docking station
And of course all the great standards of a tablet. I love all the cool software.
I take this thing EVERYWHERE. I have my planning (FranklinCovey)software on it. It has basically replaced my PDA. I use it as my atlas when I travel, and so much more. Frankly, I have not yet found anything I don't like about this tablet. I use in my practice as a physician, without limitation.

I actually just read the above postings on the toshiba. It sounds like we had very similar reasons for buying a tablet. I think the Motion would give the toshiba a run for its money on ALL the referenced features. I actually have the Motorola V710 bluetooth phone and headset. And hands down, the view anywhere screen rocks.
