I do for me I find Windows Phone the best OS on the market for what I do. The its missing apps thing I have not found to be true as everything I use my phone for there is an app for it. It is missing some games but im not a gamer and it seems most of the games are on the platform now.

As for the existence I have yet to have a issue with the device. The OS is always very fast and slick. Live tiles are great for getting the information you need without going into apps.

I also have xbox music pass and I have to say subscription music is for me the best way to have music as I here a song on the radio hit the search button and the music button and can then download the song. (I know others offer this) but works well with xbox music to as I have a surface and 360 too to sync music with.

The thing im most impressed with though is voice. I ride a bike to work and have a Bluetooth headset and when I get a text message ect it always works well when replying even with loud background noise.
