Yeah I'm waiting for the Asus ones (the ones they tweeted a pic of), preferably in orange.
I really want a case, but the ones I've seen are all hideous. So far I've just ordered a sleeve and a screen protector from Amazon so I don't leave this tablet completely vulnerable. I hope that whenever these cases come out, they'll be thin enough to fit into the sleeve because I wanna be able to carry it in my backpack without worrying (and just the case kinda worries me):-\.
EDIT: Asus would be really smart to release the cases soon. Most of the people who ordered a Nexus 7 would be interested in that case, they could be losing tons of money by waiting because other companies will start making more cases.
