I'm trying to figure out what kind of stand/case/cover thing to get and I'd like something that stands up fine on soft surfaces like mattresses, pillows, etc. Is a Smart Cover strong enough for this? If not, what iPad 2 stand thing should I get? Belkin has one listed that looks perfect but it's not out yet and there's no release date. Oh, and how are the Incase magazine and book cases? I ask especially because Best Buy has them right now and I have a gift card. Thanks.
