They'll be dragged kicking and screaming out of the stone age eventually I guess. Anyway, I just got a new very basic keyboard, and an optical mouse (with a cord). A shop with somebody who actually knew something said it was true; if you use an AT to PS/2 adapter with a cordless keyboard you have problems; with this one, it's fine. So I guess I'll stay in the stone age - or maybe bronze age? - for another year or two myself now.
