What about charles Babbage's computer? Does that not count? It was a computer, and it was his, so you could say it was personal, and, well, it didn't do very much but it was a PC! Ages before IBM!
The rain we knew is a thing of the past -
deep-delving, dark, deliberate you would say
browsing on spire and bogland; but today
our sky-blue slates are steaming in the sun,
our yachts tinkling and dancing in the bay
like racehorses. We contemplate at last
shining windows, a future forbidden to no one.
Derek Mahon
"Maybe all one can do is hope to end up with the right regrets."
