I'm not sure this is accurate for a few reasons. Again, I'm good friends with someone who just chose the Windows 7 platform so I know a lot about why he did it.
They (married couple) had iPhone 3G phones they bought after the iPhone 3GS came out to save money. They were waiting on the iPhone 5 and iOS 5 to make a decision. After it came out, they drove themselves crazy trying to decide which phone to get between the available iPhones. Android was, for them, 100% off the table due to the unique advantages of the platform, being open and android market being rather large, was completely overshadowed by the toxic user base and rampant piracy of android apps (he's a game developer). After a false start buying a poorly made Windows Phone with a crappy camera, they went back to their 3G phones. They didn't feel the cheap 3GS was different enough from their 3G phones, and they couldn't find one anyway. After numerous attempts on my part to suggest the now cheaper iPhone 4 the black friday deal came up and they were able to afford better Windows 7 phones, the HTC Titan.
Already being a .NET developer and XBox Live Games fan, he feels the bare marketplace is a great place to get started in moving to mobile with the least amount of new code to learn. Plus, no one bothers him about his Smartphone choice. Most people just want to see his phone since they are so rare. He likes this a lot of course, she is just happy to have a phone with a camera that doesn't suck. The only jokes he gets are from me, when I ask him how those tablets are working out for him, since they are HUGE phones.
As an emotional decision, these guys are non-conformists through and through. To me, the iPhone 4 was the obvious choice on their budget, but it was just too mainstream, same for Android. They joked that they were the 1% when they saw some market statistics on Mac Rumors.
So, there you go. Not some imaginary customer that I made up, real people that feel they got a good phone, at a great deal, and don't have to live with the drama of Apple vs. Android.
