There was no need to do a complete re-install, save all those files, etc. However, it seems to be slowly emerging that the transition may be far from smooth. Ubuntu forums are currently flooded with reports of system freezes and crashes. To make matters worse, no solution has been offered, other than generic suggestions about updating drivers and the last. Although the move to the Unity desktop was already controversial, this could be the nail in the coffin if the Ubuntu ascendancy. That being said, it may be a boon for alternative distros, like Mint, if Ubuntu does not address the issue rapidly.
