Yes and Wolfram Alpha is what makes things like that happen
Siri is nice when it's working. One very basic thing that it's had a problem with since the beginning is when I tell it to message a friend that has the Sam first name as me. It always asks which person I want to call (myself or my friend). I have my contact info set in Siri settings so it should know better.
The new updates on os6 are pretty good now if they can just improve on batterylife ??
