I just came across this tweet by one of the senior people at Kobo:
If you look really close at the bottom of the picture you'll see 3 icons: home, menu, and back. I'm guessing that this is an Android tablet, but it's not one I recognize off the top of my head.
Update: I should have listened to Mike Cane. The 3 icons are in just the right spot for this to be the Cruz Tablet. D'Oh!
