I've been using a Pi for some similar timers, and given the price-point, there's a lot to be said for them. The most relevant example here would be one that reads my calendar (ical over http) and only fires on days I'm working. "Doesn't fire when I'm in a meeting" wouldn't be a huge stretch either. Or at home, "doesn't fire if the lights are turned off" would stop the desk bouncing around when I'm not working. I'm not sure NTP over wifi is a big deal either. The problem space here isn't millisecond accuracy, it's regaining time after a power-off, as the pi lacks an RTC.
