Edit : it seems OK
My 2 cents:
1/ The "NFC service" eats some of the battery. Not that much, but still more than expected since NFC is not working.
2/ I reported a nasty graphics corruption in CM10 in "Tango". Same thing in CM10.1.
3/ In CM10, there used to be a whole screen to adjust custom brightness settings. I can't seen to find this in CM10.1. Bug or feature removed from CM10.1?
Otherwise, Homescreen is amazingly slick! (Trebuchet turned 1.0)
