that even by Windows 10 when the Windows Store has hundreds of thousands of apps and Windows is built hugely for mobile again,
we don't need millions of craps apps, we need only few good one. And from what I can see it won't happen with Metro Apps, it's too limited as platform for a desktop apps, unless you want a kind of apps to choose the color of your lipstick
ios and android have a whole plethora of crap apps with a few good highlights. Shoot, even some of the top Windows Phone apps are being brought over to Windows 8. The Weather Channel is there, AccuWeather, USA Today, Angry Birds Star Wars and some others. Windows Phone 8 will have 46 of the top 50 apps from ios and android, which will mostly likely be ported over to Windows 8 due to the shared NT core. By Windows 10, I would place a shot of liquor saying that those top apps will already be on Windows as well as some new and upcoming apps that have been developed on Windows and will be getting port overs to android and ios as well as of course Windows Phone.
