I have met a few people using a P4 Win XP machine with less memory, mostly for email, word processor, and youtube. The kind of PC you wait for 5-10 minutes before you can start using it. Some people are just very stingy. You will do the world a favor by convincing them to upgrade. Having said that, I personally feel bad for some of them who missed the opportunity to upgrade when Windows 7 was the OS available on cheap PCs at Walmart and Bestbuy. Now they have to go with Windows 8, and the stupid Win8 interface will do nothing to help their experience.
