A young lady recently came to me with a non-booting IBM thinkpad. It had previously contained Windows 98. I stuck in an Ubuntu Live CD, found that her data was alright, and let her play around. She loved it. An hour later Ubuntu (Breezy) was up and running on her machine. The next day I went to fix her Valknut (DC++) and noticed that she had changed the background, altered the toolbar transparency, fiddled with themes and generally set the machine up to look pretty sweet. What surprised me is that she had been too scared to do anything in Windows. Even better, her 600Mhz laptop is running faster that I could have hoped.
I was happy to use our new local Ubuntu mirror, so she can get software security updates for all her installed software instead of just OS components. It was lovely explaining to her that she doesn't need to scan for spyware every day.
That was by far one of the easiest and best 'repairs' I have ever done. We are one step closer to closing bug one.
