I'm dual-booting Fedora 17 (with the KDE desktop) on my second generation X1 Carbon.
I don't remember having any serious trouble with any of the hardware, including the wifi (which can be a pain point). Connecting an external monitor also worked fine- I think that's another common pain point.
I couldn't find a clickpad driver that would support gestures as well as the proprietary Synaptics driver on Windows (but I tend not to use gestures anyway), and the battery seemed to drain faster on Linux than on Windows, but that's about it.
If memory serves (I've had this machine for a while) the only complain I had was that booting into grub2 was noticeably slower than booting into the Windows boot manager.
I also got the fourth generation model a couple of months ago but haven't yet installed Linux on it, mostly because I can find so little to grumble about. Either Windows is getting better or I'm getting old :)
