I got the new iPhone Air really just due to the form factor; specifically the thinness. I'm not a power user (especially not with a camera which is probably where this device pays more of a price for the smaller footprint), but I love it. The battery power is definitely noticeably shorter, but that's not really an issue for me. It can go a whole day probably a day and a half without charging and that's plenty good for me. I love the device. It's really cool. In fact the only negative frankly is that there's a point where they get so thin that it's difficult to pick up. In fact, without a case you couldn't lay this screen side down and pick it up with your fingers. There's just not enough area - and with that slick titanium, one just can't get enough purchase to reliably pick it up. But again love the device.
