Well, not really. If you actually had experience using both systems and could form a proper opinion by yourself (rather than repeating another person's opinion), then I wouldn't mind it. Clearly that is not the case.
Of course you will be that guy and complain about my OS.
First off iOS is a phone/tablet OS, but I'm assuming you mean OS X.
Developing on Windows sucks. Its OS ecosystem is a mess and its lack of a proper command line is just ridiculous. Sure, you can install cygwin/others and spend countless hours configuring it to feel like a proper CLI, but it never will.
Linux is great for servers and embedded devices, but I don't really like the feel as a desktop OS - maybe one day I'll give it another try.
OS X works just fine for me. It has a nice, consistent UI with universal support for shortcuts, customization and such (without recompiling parts of the OS, etc.).
I can compile a vast amount of UNIX programs (even the Pawn compiler), make iOS/Android apps, code C#, Objective-C in a great IDE, run Adobe Creative Suite, and have a CLI that doesn't get on my nerves every single time I use it.
