This isn't specifically my situation. But I know three families in low-income situations for whom that sort of PC is the only one they have, because they got it from either an office or a school when the place was discarding computers.

They can't afford to upgrade, and they're afraid that even upgrading the software would make the whole thing come apart at the seams.
