It came on Wednesday, and I really like it. My card was not charged until it shipped.
I was interested in the ClamCase for iPad Air too, and probably waited almost until the end of summer before giving in and getting a New Trent Airbender. The Zagg was an option, but I have no need for the backlit keyboard, and I wasn't impressed with the design.
I haven't had any real problems with the case so far. I noticed that it does wobble a little bit in Movie mode. But not quite as much as the Slim Book for Zagg

Of course it adds a lot of weight, and it's a bit top heavy, which causes it to flop over in laptop mode, depending on the angle it's in or surface I'm using it on (in my lap).
Besides that, charging the iPad inside the case was a bit difficult. It was hard to plug into and to remove. Not as much with the audio jack, but at least ClamCase included an adapter. I was using Apple's usb/earphones.
But if you watched any reviews for the Air version, then it's pretty much the same.
How'd you like yours?
