I've been tweaking Ubuntu on my Macbook Pro 15" Retina now for a few days. Have you really gotten the wireless to work perfectly? The only major problem I have is the wireless disconnecting, not connecting, packet loss, etc.. It seems to be a power management issue (if I manually drop the txpower then it works a bit better for a while etc).
You can drop the txpower with:
(3 seems to work a bit better for me, by default it just uses 20 all the time)
sudo iwconfig wlan0 txpower <number>
Right now I'm running 12.10 according to the instructions here: http://cberner.com/2012/10/19/instal...ok-pro-retina/
Also tried ndiswrapper with the BootCamp drivers, but they didn't work.
