Got my Thinkpad X1 Carbon yesterday, and I've been spending all of today getting it running (Ok, that and a great drive down to Santa Cruz and back up along the coast) on Linux.
I'm here to report, it's working great. Fantastic machine, much more impressed than I thought I would be. The keyboard is light years beyond my beloved MacBook Air's, and the .8 pounds isn't too noticeable.
If you're looking to get one, wait for a Lenovo sale, but well recommended.

Shamelessly pitching my driving blog: [
