Over at MacSparky, David Sparks posted about a useful feature of Siri—at least if you’re a lawyer and you constantly need to calculate what is X amount of days from Y. (Which I am and which I do.) In short, you just ask Siri “What is X days from Y?” and she’ll figure it out.
This just made Siri about twice as useful for me. The only device I have it on is my iPad—still stuck on my old iPhone 4—but I’m usually bringing that work, anyway. No more ticking off days on my paper calendar.
