Guess you didn't read the Apple iTunes / App Store ToS.
Citing the ToS as a reason to not use something is meh at best. None of the ToSes out there favor the customer it doesn't matter which company you pick (Amazon, Valve, etc. etc.).
The itunes store is the kind of crap that prompted this. But windows software didn't have this kind of crap before, and definatel doesn;t need it now. The desktop versions still work, so just get those.
Read what again? The reason for the UI is because it works well across all device types and input methods, and allows for "write once, run anywhere" applications. I happen to quite like metro, it's nice and clean and it flows nicely from my phone to my (x86) tablet to my desktop.
You can use phone level software on a desktop, but not desktop level software on a phone. Making this utopia fail in the real world, or mean that this junk is going to be severly limited to basic crap. But there is already software that does this (webpages, browsers), 99% of phone application software is catered to by a browser, you don;t need to give up your privacy to do this.
Am I doing it right?
Kind of. But you didn't need the self portrait.
