So yeah, after today I have a new found joy in how intuitive Windows Phone is. I was wandering Toronto with my family today and I was using Tellme a couple times every hour in the loud city landscape and inside of a vehicle with music blaring with a, surprisingly enough, a 100% success rate. I wasn't even using keywords either, I was just "Where is the nearest good restaurant in Toronto is" and I got a pretty good place nearby. Then right from that menu, I was able to select Drive (Note: I have never gotten this far in TellMe before because I only use it for messages and/or to find names of places nearby, never actually selecting a place) and then go directly into Nokia Drive all within 3 taps.
I'm just incredibly impressed from this. Just the fact that TellMe could recognize me in all the music and sound was amazing.
