This will be my last comment on this thread. I do business applications for real world businesses. I identify the exact needs ( not game stuff ), and spend my time providing complete solutions to meet those needs. I have a tablet version of my software that actually provides my clients with significant benefit, and it works with their primary computers. I do not see the "death of desktops" in business, and that is where I focus my time.
I use FW for Windows because it works very well with the OS. Some time was spent with FW for Mac, but that is mostly experimental. The same would be true for Android. Windows is NOT dead, and anyone who has actually invested in, and spent time with, Windows 8 products knows the benefit.
Yes, there are more Andoroid phones being sold, but that is a combination of ALL the models. Not one of those comes anywhere close to the sales of the iPhone ! Also, there is a lot of exchanging of Android phones. They are like a disposable toy. Spend time on the carrier's forums and you will see this. People by a Droid, find its weaknesses, sell it on eBay, and buy another. User satisfaction scores are not too great in every study I've seen, while the iPhone and Windows Phone have satisfaction results over 95 %. Also, most people have no clue what they want in a phone so they go to a store and its all Android being pushed. That is because there is more profit and better commissions. The sales people will actually try to discourage people from buying a Windows or iPhone. In fact, Verizon, our biggest provider, actually weakens the Windows Phone to make it less popular. I've used them all and the Windows Phone I love the most. It is the best organized phone out there and has won many awards.
You can switch over to the Android marketing model, but unless you have an amazing app, you won't make much money with it. You will just become one more app in a store that has way too much competition for you to stand out.
So, I've said enough. I'm just an old guy with a lot of experience, and I'll ride out my remaining years continuing on the way I've worked successfully in the past. You may not agree with me, but my software development has supported my family, put my kids through college, paid for weddings, and allowed me to be very comfortable for over 30 years.
