For the last 20 years, "has a numpad" has been one my qualifying criteria for buying a laptop. I need a numpad, because I type long-ish numbers into my computer all the time. IP addresses, phone numbers, and simple arithmetic problems are probably my top three uses. If I had to suffer with only a number row on a day-to-day basis, I'm sure I'd have some kind of RSI by now. The number row is too far away from the home keys to be of more than occasional use.
