Looks like CynanogenMOD 7 (an android 2.3 mod) can be put on three tablets.
B&N Nook Color
Its easy to root/mod, so this would be my choice.
So I picked up the Viewsonic last night. Couldn't find the Nook new anywhere in canada and 299 price for 10 inch with Tegra 2, 8+ hour battery life sounded good.
Viewsonics 2.2 OS version was pretty terrible so I Installed Cyanogenmod today...pretty sweet I must say.
