Some day I will totally convert - right now I have a dual boot system on my desktop and Linux Mepis alone on my laptop.
I change it over to Ubuntu or Kubuntu once in awhile.
Those were the first 2 Linux OS I tried years ago.

I have Quicken that I really like and that is the main reason I have stayed with Windows XP . Haven't found a comparable free program like it.

I haven't needed to upgrade to Vista or 7 for anything.
