Weren't they 2800, not 2400? I always liked the sounds they made when they were dialling up.

Nobody will ever miss pagers, IMHO. I used to have to carry one to support a trading server at a bank (Credit Suisse, somewhat topically) and I used to dread it going off in the middle of the night because something had gone horribly wrong in Hong Kong. We eventually re-wrote the server so it was trivial to restart & managed to shuffle off responsibility for it to the locals. Bye-bye pager and good riddance!

Liked your books, BTW!
