The magnetic groove that the Air slots into can be bent back, now, to offer better angles at a low desk or even a lap. But it's a subtle feature, and the way it works -- by popping the plastic groove-bar backward -- feels odd, and I had a hard time bending the bar back in when I was done. I noticed one side of the Logitech keyboard's plastic housing coming unglued from its metal base. I wasn't sure if this was because of wear and tear from the bend-back mechanism.
The added extra recline is welcome, but it's not a lap-friendly device. In fact, I'm downright afraid of using this in my lap while typing. The Ultrathin's magnetized groove keeps the Air in place, but it starts to feel like that delicate but expensive slab of metal and glass could topple out at any second once it's perched on my knees.
Logitech's keyboard revision also lacks other extras. It's still not a true iPad case, just a cover. Also, there's no Bluetooth auto-pairing: you need to switch the keyboard on and off, unlike many other keyboard accessories that do it automatically. Belkin and Logitech already have other cases that do this. Why not the Ultrathin?
Logitech hasn't messed with the keyboard, thankfully. All the keys are where you'd expect them to be. And over a period of time typing furiously, the Ultrathin's still my favorite slim iPad keyboard in terms of "type feel", provided you can live with the extreme flatness and lack of palmrest. It just takes a bit of getting used to.
I just wish the new Ultrathin was even more slickly designed. It's nice to get the extra angle adjustment, but I'm not sure I'm a fan of the mechanism. Then again, if I were running out of the house with an iPad keyboard, I'd still grab the Logitech first.
