I'm 100% in the same boat. My 11" MBA has already been returned to the AppleStore.
I can't agree with this either. It's a very personal thing, but I find the keyboard "travel" to be very slight. And irritating. The keys depress so little (less than the RevB MBA I have and MUCH less than my 15" MBP) that it's more akin to typing on a touch-screen to me than typing on a keyboard.
And since I'm a freelance writer - the keyboard is my #1 thing. I *might* have been okay without the keyboard backlight, but the keyboard depresses being so shallow made me (and my fingers!) furious after an afternoon in a coffee shop.
I also found the screen *quite* constraining. I'm not old, but I do wear glasses and I found my eyes straining with the tiny UI elements. I was constantly Pressing + to get text bigger in Safari, and leaning in real close to read things.
I also read today online that the 11" MBA's UI elements are 30% smaller than the iMac's. That's insane to me. It's just too small on a screen that's already small. I wish they had kept the 13" MBA RevC's resolution and squashed it down.
IMHO, It's one thing to make a 15" or 27" high rez screen - the screen's big enough that you can still see things. But on the 11", (and again, this it just IMHO) it's just an artificial way to make a small screen *seem* like a big one, by squashing everything down and making it TINY.
I love my current MBA (13" RevB 1.6Ghz, SSD), and it's with me 24/7. And while I'd love to benefit from less weight, more battery life, and some faster SSDs, I feel that I'm gonna wait till the next rev 13". Hopefully the backlight comes back, and the key depress a little more.
