I read the first post. I know it's just an opinion, but I can't agree that there is a better range of quality software on OS X compared to Windows. In fact, I know Mac users who dual boot Windows just because they need to run certain software that isn't on OS X.
As for the Windows Store, I totally agree that it is awful in Windows 8. The initial front page looks clean, but doesn't give you a great deal of info, but as soon as you click on a category you'll witness some of the worst interface design ever created. Thankfully, that's one thing they have addressed in a big way in 8.1 as the store has been given a complete refresh and now looks like this when you launch it (open these pics in a new tab to see them full screen): -
You can right click (or swipe down) to view this menu bar at the top: -
Then when you actually enter a particular category, you get this view rather than those thin rectangular stripes from the Windows 8 store that show you pretty much no info: -
It's vastly improved overall IMO.
As for this: -
Well, one thing might just be that study after study has shown that Apple users are more likely to pay for their apps, unlike Android users who hate paying for apps and will find any way around paying when they can.
Bit of a generalisation isn't it? lol. The "problem" with Android in terms of apps is its openness. Without modifying the phone in any way, you can download a tiny APK from the web, pop it on your phone - which again is easier on Android because you just hook it to your PC with a USB cable and drag and drop, so no software is required - and that's all that's required for piracy to occur. Google did attempt to address this in JellyBean using app encryption, so a downloaded APK is tied to the device that downloaded it and the user account, much like how XBLA games work on the Xbox 360, but it was problematic so they had to disable it.
I think that if you could do the same thing on an iPhone, piracy would be just as big an issue. Also, there are a lot of ad-supported, free apps on Android that do a particular task perfectly well, so people will often choose those instead of paying for an app that does the same thing, but doesn't have ads.
