Coming from an iPad 3, I used use the logitech ultathin keyboard case with it and I was very happy with it. in comparison to the new updated one for the air, I just want to mention a few things for those that maybe looking at purchasing one for your new air. Pros: 1. the keyboard does have the magnet sleep mode when closed 2. they improved the "strength" and size of the magnet on the keyboard, it really does take some force to remove the keyboard from the iPad 3. to prevent scratching the bottom of the keyboard, there are now a large rubber piece that runs parallel to the locking magnet and 2 small rubber feet that not only prevents scratching but keeps the keyboard from sliding around. Cons: 1. My biggest gripe is the area where the iPad sits on the keyboard when in use: the previous model, literally locked in (I'm guessing with magnets), and you could carry your ipad with the keyboard locked to the iPad (ie. moving from the dining room table to the couch etc.) The updated keyboard has such a weak magnet that carrying it this way, is impossible. (I've had to be ultra concious not to carry or move around the air like this, as I've nearly dropped the keyboard twice now) Overall, logitech did a great job with the updated ultrathin keyboard for the Air. Has the great key response that we are all used to, and it looks great matched up with the air. Although the weaker magnet for the keyboard connection was an annoyance, I'm still very happy with it, I didn't go with the folio, b/c honestly I didn't like that the caps lock was the oversized "A" key.
