Just wondering how many of you who have the iPad Air use it with a case or do you have it bare naked? The Air is so nice and light that putting a case on it makes it bulky. I bought the Targus Versavu which is a nice case, but add almost a whole pound of weight. I took it out of the case and wow...what a difference! I hesitate to keep it this way unprotected in the event of a drop or something. What do you think? Do you put yours in a case?
