An old friend of mine who I haven't seen in ages just texted me. He says his father, who recused my suggestion to clean his HDD for him instead of actually hiring someone to do that, asked me to "fix" his computer.

Me: Well, what's wrong with it?
Him: Nothing, it's just that his PC is really slow. Remember he uses a Vaio?

My best hope is to get the poor dude an running Xubuntu on his machine and hope he adapts to it.
