It would have been fine if they kept using the term ‘Metro’ for the modern apps (Windows Store apps?) but for some reason Microsoft forgot to do their due diligence on whether they can legally use that name or not before they started using it.
So when they realized they had to stop using that name, they started calling them ‘modern apps’ for the lack of better words. But that’s not gonna help differentiate the type of apps since any application (whether a Windows Store or Desktop app) can revamp their UI and call it modern. Modern isn’t a noun, it’s an adjective. It can be used to describe any application if it fits the definition. So by calling them modern also added more confusion to the developers and end users.
So when Microsoft realized that, they changed it a second time and told us to start calling them ‘Windows Store’ apps instead. But any Windows 8 or Windows RT ‘app’ can come from the Windows Store eventually, and calling them Windows Store apps basically tells us that the app came from the Windows Store and not what type of application it is (I’m talking about what an average consumer would think).
So calling them Windows Store apps isn’t gonna help either in the long run and will most likely (as it is already) add more to the confusion.
Personally, I have no clue what those apps should be called, but I did like the term ‘metro’ the most out of all of them. Unfortunately, ‘metro’ cannot be used anymore.
Get your shit together, Microsoft.
