I use a 13" Air (3,2) - 2010 model - and I have been running Ubuntu since getting it in 2010 (OS X is still installed, but very seldom used). Much the same story as squidsoup, apart from the sleep issues (it's been acting up _very_ occasionally for me, one or two times since I got it).
My trackpad is very sensitive, prior to 12.10 I used the "multitouch" driver, which doesn't seem to be maintained (I got it from the mactel ppa [1]), so now I use the "synaptics" driver which seems to me more configurable but I haven't experimented much.
That said, I've gotten used to it and it's still a better trackpad than any non-Apple laptop I've used. I would like to find a good config for this laptop, though!
It tends to run quite hot. The battery still lasts over five hours, after more than two years daily, heavy use. That's impressive.
Edit: The only thing that was really cumbersome with Ubuntu on this was installation: I installed from USB and Apple makes that really difficult, as you can't boot off USB unless you're Apple. Instead, you have to partition the disk and flash the installation image to the disk (and you have to write it to one of the first few partitions, which I didn't at first).
