Is there a way to find a list of commands etc? I tried using it several times last night, mostly trying to get directions. On my S3 I could say Navigate to blah blah blah and it would bring up turn by turn to my destination. ON WP8 it kept opening one note and creating a note that said "Navigate to blah blah blah" Not so helpful lol.. I tried several different commands but none seemed to work with regards to directions etc.
I asked, "Where is the closest movie theater?" and it gave me a search of movie theaters - not really equivalent to Siri, in my opinion. I am interested in seeing how it handles other requests so I will keep testing it.
