The fragmentation debate is about to get interesting. The Apple App Store is currently divided into 2 sections. One for iPhone/iPod Touch, the other for iPad. This is, I suspect, due to iOS not allowing resolution scaling. Now they are introducing 2 new form factors to their product line. The iPhone 5 and the iPad Mini. So, does this now mean that there will be 4 sections to the App Store? Where if you publish an app, you now have to make 4 different versions so that your app is compatible with all available form factors?
I also heard that if you bought an iPhone app, and then get an iPad and want to put that app on your iPad as well, you have to buy the iPad version separately. If this is true (I do not know as I've not owned an iPad), and then there has to be 4 different sections, then that is going to aggravate a lot of customers.
At the very least, pushing the need to scale on the individual app developers seems kind of wrong to me.
