This type of news really breaks my heart. I'm part of a team developing a Windows 8 app for Metro. On the one hand, we have faced lots of challenges (8.1 isn't compatible with 8!) and understand the issues regarding adoption. However, we still continue to believe that the Metro experience is a great concept and apps like ours have a chance to significantly turn the tide on its reputation. It's really a free-for-all where whoever creates the strongest end-user experience can really own that category on Windows 8. That brand/product recognition can follow to a user's other devices whether it phone/tablet/laptop.
