Microsoft's biggest enemy: Microsoft
The whole WinPho thing has turned into such an epic own goal, and after such a promising start, too.
I mean, here we are with Microsoft being all "Hey we built these really good native apps for Android! Use our stuff on your existing phone!" and that's great, well done Microsoft, you should have done that years ago - but answer me this: If you can build excellent native office/skype/whatever apps for Android, how come you couldn't do that for Windows Phone?
Seriously, how did you fuck that one up? It's like admitting that you've screwed up the WinPho development API so badly that it's easier to write your client software for someone else's platform than it is to use your own - despite the fact that the developers of Office for WinPho should be better placed than _anyone_ to get the very, very best out of the underlying OS.
