Absolutely! I don't get asked a whole lot, but don't mind helping because of the reasons you point out and also because it keeps me sharp. One thing that is really helpful is that I always have the friend drop his computer off at my house so I can work on it in my spare (sparse) time with all my tools at hand. Nowadays the computers are mostly laptops, but even towers are easy enough to transport (I have plenty of keyboards, mice, and monitors). Trying to fix a computer in real time on-site or over a phone is a major PITA.
