A friend brought over a laptop that someone had given her. She couldn't figure out how to use it and I said just bring it over, I'll check it out.
I turned it on and was totally mystified by what I saw. It was a Dell laptop and had Linux installed with a Freesbee desktop. I couldn't figure out how to use it either. Happily I had an unopened unused fully licensed WinXP Pro hanging around so we stuck the cd in in and said "yes" to remove the partition and "yes" to reformat. 
Don't get me wrong - I am not an anti-opensource bigot. There was just no way that either my friend or I was going to figure out how she could use this quickly when she already was well-versed in all things windows.
