Imac G4/700: Upgrade vs. replace?

[mrlynn]

We have a G4/700 iMac, too, with a bit more RAM (768); doesn't get much use these days, except for an occasional family iChat, but it's perfectly capable of surfing the Web and doing email. So if their usage is basically light-duty, and they're not complaining, I'd vote for some additional RAM and some housecleaning (those HDs were small and filled up fast; also repair Permissions and clear caches).

Faster Internet access might be more important. Can't run FIOS or cable over the air? Maybe the IPs would be willing to do some digging in return for a longer contract.
