Some of the so-called "techs" that advertise their services are pretty dumb when it comes to the new hardware and software. I've talked to several who are still hanging on to old modems and CD drives (note, not burners) just in case. Of what, I don't know.
While most people who need tech services won't need someone who knows about C2D, AM2, perpendicular recording, PCI-E2, and such, some will. Even popping a SATA drive on these idiots will give them fits because they have no idea of how to hook it up ("It ain't got a big enough interface for the cable!").
I'm almost the opposite. A lady at work had me work on her computer (cleaning out adware/spyware mostly). it was running Win98. I actually had to go to Google for a couple of things... because the operating system was so old (and I couldn't remember where to find some things that are in different places in XP).
