I bet it's 6 hours actual usage. Apparently the Galaxy S has great battery life (around the same) and can carry individuals through a day with heavy usage. With a bluetooth headset that you can answer calls with, the tablet can function just like a phone, though holding it to your head would be a bit much.

Indeed there are many tablets coming! There will be a 10" Tab from Samsung as well. These tablets look really good. Some of them are running Tegra, which is very tempting as well!

I'm looking forward to seeing the UX upgrade in store for Android3. Since they captured that palm designer guy, Android is in store for quite a UI upgrade in subsequent devices, and I'm sure it will have among the best UI, as well as be more suited for tablet devices!
