What do I want from my Windows Phone?
Wireless and/ or USB tethering.
Voice-to-text for everything from searches to SMS.
Official Google and YouTube apps. YouTube should be fully integrated and it should be as easy to upload a video to YouTube (or Facebook) as it is to share photos to your SkyDrive or Facebook.
I'd love all the other Google apps and maps.
Bing had turn-by-turn voice navigation on Windows Mobile just recently. Why not on WP??
Also, I'd love it if we could set your position on the map to be shown as an arrow pointing either North with a rotating map or if the arrow is relative to the direction you are traveling which leads me to...
A good compass app. The HTC one on my last HD2 was great.
Also, I think it would be cool if we had a WebMD symptom checker app. I'm a new father and always go nuts wondering if my baby's showing symptoms of being sick or not and a symptom checker like the one on
www.webmd.com would be great.
I have other ideas for apps but those I'm saving for myself if I decide to start making apps soon.
