Comment 81 for bug 1034002

I don't think I ever had a release prior to precise running on the laptop -
I was using the development ISOs when I first got the machine about 2 years
ago. As I recall it was really hard to get it running at all (I had to use
the server CD) - things have improved since then ;-)
