Great. I like Media Center + 360 integration (if marketed it could be huge, yet so few of PC owners are even aware their PC & 360 can do this), and a big fan of Windows Mobile - but there are still ridiculous gaps in integration of MS services.
The XBL integration with Windows Mobile (as Live Anywhere) was shown in early demo form almost 2 years ago and now recently only a Zune XBL mobile integration is being discussed. XBL Anywhere integration with Windows Mobile devices (most of which are internet connected at all times) would have been a killer app that would have driven cross-platform adoption like crazy - where is it?
The content in the XBL Video Marketplace service can't be shared with (transcoded to) Zunes or Windows Mobile devices - with content availability being such a key driver of platform adoption, and Apple providing content sharing between iTunes, iPod/iPhone, and Apple TV, MS has missed another opportunity to gain cross-platform market share.
