Good integration of WindowsPhone into a MS Windows regular PS network, see explanation
I left iPhone because I didn't want to have iTunes and Bonjour anymore. I got Zune, sadly. However, I found not acceptable that a Windows Phone does not allow me to navigate, at home, into my personnal network and to, for instance, stream documents, music, films, etc... Instead I have to go for Skydrive, limited to some Gb!
By following the Apple iCloud idea, WindowsPhone will just loose its best customer target: the regular PC-Windows (XP, Vista, Seven).
No DLNA, no WORKGROUP, no remote, no access to the media without Zune !!! Even iPhone is able to do that !!!
I was an iPhone user, and I've lately changed for WP because of the Lumia800 and the hope of a full integration OS with W7...
