I have the x220 tablet (arch linux on it) with the multitouch option and it's definitely matte. I can't compare it to the build quality of the x201, but I'm pleased with the performance and display. 10W power consumption with wifi on after a bit of powertop2.
I've had some questions about the matte screen and will post this here for reference. I've compared it to my matte cinema display and my glossy cinema display. It's not as matte as the 'actual' matte display, but the x220 with multitouch layer would definitely count as a matte screen in my book. I'll try to get a picture up on the arch wiki.
