From the moment I got my Mini 12 it has been nothing but problems. It is basically unusable, as it hangs all the time. The first weekend I had it I went through several steps to troubleshoot, including reloading XP several times; Dell restore, XP restore, fresh install, fresh install with a different CD and finally installing Ubuntu. Even under Ubuntu it still hangs. Just out of the blue the entire system is locked up.
I called Dell support and they agreed to replace the defective unit. That was about 4 weeks ago, still no replacement. They say they are having shortages of LCD screens for the Mini 12.
This has been a very disappointing experience with Dell.
