Just installed the latest CM 10.2 UNOFFICIAL on Saturday night. Started with the official 4.1.1 JB from ASUS (10.4.2.18), unlocked, made NVFLASH recoveries, flashed TWRP 2.6.3, then flashed the CM ROM. Works great, including the power button. Don't have the keyboard dock, so can't speak to those problems. Only real issue for us was make sure you clear all the stuff before you flash the ROM (and we did it again after as well).
