@SteveRichter: I disagree. I like WinPh a lot despite they crippled Mango Bing Map. I like it a lot. All WinPh hare high quality and performance really well in expectations. No hidden apps to drain my battery. There is a few, but, it is easy to disable them such as play music from Music app and launch a simple game, can easily stop apps that relies on background process.
