I might buy one of those super cheapo Chinese ones sooner or later just to see what it can do, but I'm not buying an $800 7" screen Galaxy tablet.
I wouldn't reccomend doing either of those things. Most of the cheap Chinese ones have zero support, no marketplace, and in general perform poorly. The Galaxy performs fairly well, but it's way overpriced.
Wait a couple months until after the holidays and you'll see quite a few released for around $300. The Notion Ink Adam is the one I'm holding out the most hope for, but the lowish screen resolution makes me nervous. Unless it receives stellar reviews, I'll look into the Acer high resolution tablets when they are released.
