I, too, own a computer repair shop. We've been open for a few years now, and while I don't have any numbers on me at the moment, this seems very similar to our early days. We're in a very small town, so our numbers probably started off a bit lower.<p>We do a lot of: virus/spyware removal, replacing broken power jacks on laptops, hard drive replacement (with and without data recovery), in the spring/summer we replace a lot of power supplies thanks to all of the thunderstorms), format and reinstall (usually at their request, we rarely have to do it due to viruses, etc.), RAM upgrades, laptop screen replacements.<p>By far, the majority of the hardware problems we see are hard drives and laptop power jacks, which makes sense, since they tend to take the most abuse.
