I did a test run of Zorin 12.1 --64 bit on the CF52GUN. I really liked it so I pulled the SSD and gave it a permanent home in the CF53A. I set it up with the OSX look and feel. I used the FEBE extension for Firefox to save my profile from the Win7 install that was on the CF53A. The touchpad does not scroll properly. --2 finger scroll was enabled. Disabled it and edge scrolling works. Other than that everything seems to work fine.
