I'm currently using Windows mostly because I didn't really want to spend the money on a mac when I got my computer. I guess I do like Windows 7, it seems very easy to mod. Which is could because the normal windows 7 look just wasn't my style....
I use Windows for games and some specific programs, Linux for everything else. In a nutshell, these are the main reasons for my OS choices:
Linux: - Versatility and flexibility: it can be scaled to perform well on both high-end systems and computers that are about a decade old. Support for a variety of CPU architectures and filesystems are features most users won't find that useful, but in certain situations, having such options available can make a big difference. - Speed and resource footprint: because of scalability and having numerous distributions available out there, it's possible to use only the programs and system elements that I need. Nothing unnecessary. - Customization options: this is probably my main reason for sticking to Linux. Once I've got everything running smoothly and just the way I want it, there's little out there that can bring me be back to using a different configuration and different OS. - Control over everything the OS does. I'm just the kind of person who likes to know what happens under the hood.
Windows: - Compatibility: it's mostly related to games, of course. There just aren't any other options for some of them. - Ease of use. Even though it's usually very inefficient system resource-wise, it's often easier to accomplish some quick-and-dirty task under Windows. For times when my brain needs a break.
The laptop I currently use has Ubuntu 10.04 installed, but once I receive the necessary hardware replacements for my PC, I plan on setting up an Arch Linux/Windows 7 dual-boot system.
Pros - Extremely user friendly - Light laptops - Good for graphic design and video editing - Nice file management system - No virus's
Cons
- Sucks for just about everything else (Gaming, multi tasking, ect) - Terrible hardware - Unupgradable - Only made by apple - Extremely expensive - Almost no programs work on it compared to PC
Summery Macs are terrible and i would completely regret getting but i only keep it because its a laptop.
Windows
Pros - Much faster - Better hardware - Better gaming - Produced by multiple companies - Upgradable - Much cheaper
Cons - Virus's - Worse laptops (size wise)
Linex I haven't used it due to my lack of time to figure out how to set it up but I am guessing it will be better or worse depending on how good your computer is.
Summery
If i have a mac (which i do) i would get a laptop (which i have)
If i have a PC (which i don't) i would want a Desktop (which i don't have)
Though i can get the best of both worlds by loading one operating system onto the other computer.
RaijaRadiance took the words out of my mouth. Once I get around to it, I'll adopt Linux as my main OS. I don't feel like messing up this one computer I have.
