I got myself an otter box case but i don't think you Lose the slim and sleek look when you get one..to me...its still pretty slim And it surely does protect the device. I move around with mine a lot too and my girlfriend has already dropped it once. That being said it does add some bulk..and you may not be comfortable with that..so I'd say go to walmart and try to see if u can get it "fitted"
And most of all congratulations on the iPad. Lol
