Do you use BOTH? Or does one sit in the corner of the room and collect dust? I have an iPad 2 sleeve I bought off of etsy, but it's just a sleeve. I would like to purchase an iPad case because I'm on the subway/bus a lot and don't like using it caseless on public trans. To those with more than one case, do you regret buying another one? Or do you use both enough to feel you didn't just throw your money away? Thank you. This thread isn't for the people with 5 cases. I'm asking if I'm irrational for buying ANOTHER case for my iPad 2.
