Is this another GoogleGame?
Is this another inside joke that I'm on the outside of? Why is everyone Googling "What was the name of the first personal computer"? (And why aren't you Asking Jeeves, which can parse a plain English question?) Not that I'm not happy for the page views...

You may be trying to find this page of Personal Computer Milestones, which concludes that... Oh, why spoil their fun. Go there and see for yourself. I'll accept their answer.

Their definition includes this provision: "It must be simple enough to use that it requires no special training beyond an instruction manual." By those standards, I would argue, we haven't built one yet.

(By the way: I asked Jeeves. Nanny nanny.)
