Not to be a downer on your opinion there, but what I can tell Android has issues with malware too. The issue at hand isn't the operating systems, it's their users, always has been. If you're going to watch free episodes of "xxx favorite show here" online through a browser you're going to run into some sites with bad ads that put spyware or malware onto your pc. That's your fault, not Windows.
While yes, Linux based OS' tend to not have any issues with malware/viruses/trojans, because a bad ad is written to hit the most amount of people and the most people to hit exist on a Windows OS, not a Linux one.
Android's market share has went up, even though it's based on Linux it's seeing issues with malware because people are programming it for that OS.
Viruses exist for mac and linux, there just aren't enough people using any kind of Linux/mac OS out there, and not a lot have been made so it's harder to run into.
I was force fed Win/Intel by my school growing up, and I use Win/AMD for personal use and Linux for work (dev/hosting etc). Because I did the research on the operating systems and have used all of them.
Apple - 100%+ Upscale on hardware, and people buy it anyways. OS + Hardware
Microsoft - A little expensive in the retail value of their OS, but most of the market still uses it, business and personal. OS + Software (Slowness? It's your hardware duh!)
Linux/Unix - Free, Open-Source, free programmer driven. OS
Google - Taking Linux and making it useful for phones and tablets, cheap/cheaper to use, but an App/widget driven OS. no Full fledged desktop GUI.
Each has it's uses (though I question Apple, a lot, I appreciate them in the marketplace, but they are ignorant and picky towards retailers for an over priced System + OS combo. Don't sell 50% of your IPAD 2's with Apple Care? YOINK NO PAD FOR j00, one less place for our overpaying customers to get product from us!)
