The smart cover seems really nice, probably best for 'local' or around the house use. being able to prop it up for typing on a table or something looks cool. Some sort of clear skin for the back plus smart cover would be nice. I'd say for a lot of mobile use or travelling around having it in some sort of case (like the original apple one) would be good. Everyone has their own preference though.
I think I'd get a smart cover (seems like almost everyone would, just from the marketing of the damn thing lol).
yeah i know... i may just get one and see for myself ... i'm thinking of getting a gel skin as well ... check this out http://www.gelaskins.com they're totally cool
