You laugh but it is a seriously good thing. I mentioned the 'side project' I had submitted that Google legal had rejected, it was combining Siri with timers and cooking facts as the ultimate kitchen timer. As the GP points out, there are a bazillion factoids you might consult while cooking and a huge win for cooking is having everything come out at the same time (co-ordinating timers) so as an app on your phone following you around in your pocket it can be pretty killer.
