ATT has: 592Mb(ROM) + 512MB(RAM) + 128MB(One D-RAM) + 16GB (User Memory), + microSD slot.

Sprint & Verizon: 512MB(ROM) + 512MB(RAM) + 128MB(One D-RAM) + 2GB (User Memory) + 16GB microSD installed.
Sprint & Verizon's Tab is NOT RECOMMENDED.
Purchased a Archos 43, Android 2.2 for my son. Smaller internal memory @ 256mb + 16gb user memory. $250. Was $220 at Amazon last week. Front & back cameras.
Archos also offers other Android 2.2 tables:
28, 32, 43, 70 & 10.1. Numbers indicate screen size: Archos 43 = 4.3” diag. screen.
Archos 70 comes in 2 flavors: 16gb flash (+32gb micro SD, not included) & 250gb HDD. These run 1/2 the price of Galaxy Tab. No back camera on the 70, which is keeping me away from buying one.
These can access the Android market with an easy patch. www.archos.com, http://archosfans.com/forums/, http://forum.archosfans.com/
Advantage of Archos, they will play .AVI files & .epub.
(disclosure: I work for a company owned by Toshiba)
What about the new Toshiba tablet that’s supposed to be coming out? I’m more interested in that one, as it’s specs look to be very similar to the Motorola Xoom but without the outrageous pricetag of the Xoom.
