Unlike Jeri, 'my' Gateway, a W98 castoff that was given to me, is still going strong and co-habits with a big double-sided scanner/copier for which no no-later-than-W98 driver exists. But it isn't on the web, and doesn't get viruses.
This computer is on XP and I'll keep it until Microshaft stops the support. Like Leeneia.
I don't do anything that requires a lot of grunt. Since updating Microshaft O/S systems is an expensive option, this one will probably go onto Linux and I will have to learn a new 'language.'
