Totally agree! For the most part, "everyday users" don't really realize that all OSes are generally driven by the same technology. The main difference is the approach to the filesystem. I compile software in Linux sometimes just for the hell of it. There are times that it's taken me all day and, on other occasions, only an hour at most.

I run Windows 7 and Ubuntu 12.04 in a dual-boot configuration. I haven't even tried Windows 8 and have no desire to do so. Being a web developer, however, affords me the luxury of multiple choices when it comes to OS selection and usage. At my day job, I use Mac OS X, mainly because that's the only option. At home, as mentioned, it's Windows and Linux; Windows for gaming and media intake (movies, music, etc.), and Linux for my personal programming and web dev projects. Looking at Windows 8 on the horizon, I've also wondered what will happen when it finally drops. It's a major shakeup on the Windows desktop, for sure, which is why I will continue using my current config for as long as possible and, when I can no longer run Windows 7, I'll probably just switch to Linux full-time. OS X and iOS are great platforms, but I really don't want to spend the money for the hardware costs associated with adopting Mac for my desktop needs.
