Just finished upgrading my stock 11" 2010 MacBook Air (2 GB RAM, 64 GB SSD) to Mavericks. The update process was remarkably seamless, probably beating my 10.5-10.6 transition as being the most invisible OS update that I've seen. I'm usually loathe to do direct updates; instead I usually just do clean installs. But the update from 10.8.5 worked perfectly.
Performance is as crisp and snappy as it's always been on this machine; I haven't seen the chronic sluggishness that Lifehacker's been complaining about. I also haven't yet seen a Siracusa-esque massive jump in my battery life (though I may need to calibrate the battery to be sure). I'm also amazed at the fact that far less of my stuff has been broken than I expected; even the old, hacked copies I have of Bjango's old widgets (iStat mini, Organized) still work. Even Glims still works (though I had to reinstall it, along with XQuartz). I also unexpectedly got back an extra 1 GB of space on my machine.
The only thing I've had to be concerned about is managing drive space on this Mac's tiny SSD; it's a nice touch that the installer deletes itself after your reboot into 10.9 to give you back your 5 GB of space.
