So what can this Siri thing do anyway?
I long pressed "Home," and said "What's tomorrow's weather?"
It worked!! Well sort of. It was in Fahrenheit. I live in Canada where we base our temperature off the temperature of ice :)
I went to Settings > General > Siri, and double-checked my region. Set correctly. Weird.
I tried asking Siri, "What's tomorrow's weather in Celsius?" Same answer.
I searched the web. Found that you can change a setting in the Weather app. Unfortunately, the iPad doesn't have such a beast. Well, so much for that. I was disappointed. What a terrible oversight.
Decided to try my google-fu again today.. and found the answer here. You change the settings in the Clock app.
The Clock App? Good Grief.
At least it gives me the weather the way I expect it to now, but Steve must be rolling in his grave.
