Judging from my friends and family - one that constantly needs to be fixed or upgraded by me. HPs, Compaqs, and E-machines that have been FUBARed by a Best Buy tech, and require me to undo most of what their fix-it utility "fixed." Most likely one that will require me to spend 2-3 hours on it, and then have to break the news to them that they will need to buy a new piece of hardware, which pisses them off because they figured it would cost them dinner and a few beers.
