A 9" or 10" tablet? I'd just go all out, and buy a HP TX series tablet notebook. The N8x0s fit their niche market well, and shouldn't veer too far from their origins.
you can buy fujitsu stylistic tablets of older spec very cheaply on ebay these days, ideal for a combination picture frame and home controller. indeed, if you had "alertme" you'd have pretty much everything sorted!
