Wife stole the device (momentarily) ...
... so here are my comments so far ..
Extremely responsive screen
Wow! I mean, wow! ... really responsive, the screen itself and how the operating system reacts itself. Zero or no lag. I would say as fast as an iPad and better than Nook Color.
Full Android Market
No hacks, no rooting, nothing! It works out of the box! Kindle and B&N apps installed already and work perfectly. Is not that cool?
... is like a Nook Color with steroids, hahaha...
Light!
13 ounces! Yes, only 13! Just a bit heavier than Nook 1st generation and 2 oz less than Nook Color. Weight is more a relative thing than a fact, but when comparing with other tablets this one is way much lighter. You can't go to B&N with an iPad under your arm, you can with this baby.
Super fast Internet
I do have high speed connection at home but the browser itself (I installed Dolphine from Android Market) is super fast. I barely tested the Tmobile 3G but fast enough to email and browse Internet with the HSPA when available; I do need more testing on that. I also read (have not checked yet) that is smart enough to switch between 3G and Wifi automatically.
And of course, accelerometer for landscape, pinch capabilities, 2 cameras (front and back)
For my wife's magazines, "on the go" Internet needs and sporadic Kindle/B&N usage (on same device) this tablet is awesome! Not a replacement for my Kindle 3 or Kindle DX though.
