1. the Zatab weighs 1.4 lbs, the atom device you list weighs 2lbs. For me, even 1.5lb tablets I own(ipad, HP touchpad) are a bit on the heavy side, I don't think I would want 2 lb 2. The battery life on the Zatab is 14 hours, battery life isn't listed on the atom device, but a unlikley best scenario to be 7hrs, and could be quite worse than that. 3. It doesn't list what video chipset it uses, but most of the atom tablets use the Poulsbo chipset, which is somewhat problematic in linux, 4. The Zatab has a 5 point multi-touch, the atom you list has two point multi touch 5. The Zatab has an IPS panel, the atom you list does not 6. The Zatab has a microsd slot, the atom does not. 7. The atom comes with Windows 7 Home Basic, which since this is a chinese seller, this is the one Windows edition that has an emerging market price, I'm guessing it costs them less than $20
