T420

Hi, I will get an thinkpad T420 next week and did some OS research because I'm not sure which OS to pick for it. Currently I'm running Gentoo but I'm not 100% happy with it. I wanted a source based system and stay on the linux side of life ;) (so FreeBSD was out, too). So this is how I came to crux. I'd like to know if someone has an T420 and can give me some feedback whether everything works fine and so on... Best regards, Sebastian
