Works for me, on my 12". I am burning a dvd at 2x as I type, and tried a dvd-rw just to see if it would take it which it did. Also I have a kensington usb fly fan on my 12" just to make sure it stays cool. Anyone used this fan? It works like a charm so far (when plugged in...haven't seen how fast it will drain the battery yet) Thanks for the firmware update, I have been dying to burn at 2x, it saves me about 1/2 and hour for each burn.
