So you like WinPho7. Great for you. I don't, and don't consider it the best platform out there. That's purely subjective, and I never deny people points of view on subjective matters.
So, how can iPhones be cool when 'everyone has one' (by everyone, I assume you mean a significant segment of mobile phone users, not everyone as in everybody, mobile phone user or not)? How can surfboards be cool when all the surfers have them? Hmm.. Conundrum. Could it be that 'Cool' isn't related to how many people use something? I use mine as a dive log, gas mix aide memoir and weather checker. No fart apps in sight, and it does what I want. I rip my own CDs to whatever quality I like, and don't buy through iTunes. When I first purchased one, I did a spec of what I wanted on a phone, evaluated all the possible candidates, and settled on the iPhone as being a little more of what I wanted than the other candidates. If this approach is being "a sheep", so be it. I call it getting what I want, and what works for me best.
Android: Weird that most of my non-tech mates use Andriod, and love it (subjective opinion there is that it's highly polished, and well integrated, completely contrary to your opinion). You have an open store, which is subject to this malware, but there again, any 'unmoderated' app store is subject to the same. All phones will likely be subject to malware, with attack being based on the share of the market they've obtained (Android, being successful will be attacked a lot. WinPho, assuming it remains an 'also ran' will not be attacked so much in probability, though it's likely just as vulnerable).
All in all, you seem to be saying "This is my subjective opinion and speculation, therefore it's fact". It's not.
