Re: Microsoft made it clear that security has taken a back seat
It also eliminates the whole point of making this change. Why do you need a new API for Windows apps when there are no benefits, other than "easy installation from an app store". Seems like they are just following Apple and Google there, when the process of installing Windows apps wasn't a problem before, anyway.
So now developers have a new API they can target, but what is the benefit to them that would make them choose this over writing it as an "old school" Win32 app? Because cutting out the majority of your market (Windows 7 users) doesn't make me think any of them will be interested in this. There is no Windows Phone market to be concerned about, and Surface is basically a laptop so doesn't need touch support in its apps. Benefit for new API == zero.
