It's a buggy mess IMO. I'm running 11.04 on recently purchased Lenovo X220 (replaced my 3 year old MBP) and I've had frequent hard locks in X, windowing glitches (windows doing weird things, scroll bars acting up), and issues with cleanly shutting down and rebooting. I blame the lockup/windowing issues completely on Unity and I've had more success with the system since I've switched to the classic Ubuntu desktop. My current Linux desktop is running 10.10 and it will stay that way for the foreseeable future (perhaps until 11.10). I have a new sandy bridge desktop coming in next week and I'm undecided as to what I will be installing on that system.
