As much as I like the air, I have to agree.
Fix the screen lines, give it a 256SSD and 4GB of RAM, and I'm on board.
Screen lines are apparently fixed as of Rev. C. I've seen mine, a colleagues and two in the local Apple reseller, none of which had lines. On the A's it seems to be quite common.
256GB SSD in 1.8" with LIF connector would drive the price back up over $2k easily and I don't even think anyone makes one. Toshiba only recently announced a 256 1.8" SSD, but there's no word on whether it would fit in the MBA, let alone whether they will make it with LIF connectors.
4GB RAM I wouldn't mind. But not a deal breaker for me.
I can't see Apple hiking the Air back up to the two and a half thousand mark after seeing the huge sales boost the line got from the dropped prices.
