I honestly believe half the people in this thread are just ignorant.
Ignorant because they don't know how to do things in a OS they have not used. Imagine starting from scratch and having to learn windows inside and out, it won't happen in a single day.
I would say in some ways OS X is more customisable/useful features then windows. It's also true that for the most part, if there's a problem or issue with Mac OS X then there is usually one way to do it. Compared with windows and its method of 10 different ways to do the same thing.
Terminal is no different to command prompt in windows. Preferences in OS X is the same as control panel for windows.
I'm not a 'fanboy' as such, I still have my pc which I've built but I now use this purely for gaming, occasional ms office work. Everything else on the iMac and that's with a handful of third party apps installed. It goes to sleep rather than needing to be shutdown all the time and barely shows its age in day to day use. I also have a MacBook Unibody which was my first Apple Mac. And yes the build quality exceeds any other laptop I've tried, seriously go to John Lewis and stroll down the laptop isle.
Remember a Apple Mac is a PC. It's the software that is unique to it, and it helps that the software is designed for the hardware and vice versa.
