Viewsonic's GTablet is now up for sale from officedepot.com in 400$. Spec wise it is tegra2 based 10 inch android tablet capable to run 1080P videos. Viewsonic has customized UI based on android 2.2. Most important thing is that with such a high spec, it still claims 10 hours of battery so a serious competitor of IPad. I don't know why viewsonic didn't spend money to market it like samsung did for Galaxy Tab.
