Welcome to the world of Ubuntu I've been converting Windows
users to Ubuntu for a while and whilst most take to it there are those
who just don't get on with it and ask to be put back onto WinXP.
Various reasons but some as weird as missing the Windows versions of
Solitaire and Free Cell - even though these are in Ubuntu too

Some folks just don't get on well with change but for some reason are
more willing to accept it from MicroSoft .... funny old world !!
