I've been telling friends this for years, but there are still a few die-hard people I know who bring their computer into BB at least once a year for a "tune-up" that costs them to the tune of $100+.
Seriously, I have to go check this one out one day for myself and play dumb at the local BB to see what they are willing to tell me to sell me services and junk.
