Mac OS X Leopard

Adam: Why not? Windows isn't the greatest OS around, but it still is the gamers OS of choice. And since gaming is my main hobby, it was the logical option for me, since on a Mac, I would have installed it via BootCamp anyway.

Virusses: I have an antivirus program as a precaution, but I never find it to be necessary, since I buy legal software from trusted companies and don't have the need to click every single porn/celeb/gossip link I lay eyes upon :P It may be simplified, but 90% of Windows virusses can be traced to this... And do you honestly believe Macs can't get virusses by design? They have security issues just as well, but not getting virusses will typically be the advantage of the niche OS. If Windows had only 5% of the OS market, and OS X were dominant, you can bet your lucky stars OS X would be the new virus playground... It's a fact of life that malicious programmers will target the dominant OS, simply because they can harm a greater amount of people.

For the price: I actually prefer clones, since that way I can make sure everything is compatible and I can cut costs on hardware I don't need anyway, like a built-in wireless and Bluetooth adapter and a remote. Not to mention I bought a superb motherboard, so that I'm sure I can upgrade it piece by piece, my Core2Quad will easily be ok for the next 5 years. And my screen is Full HD and I don't like them bigger than 22" anyway, so that thing will last me until it breaks and is out of waranty, which would probably be 10 years. My next laptop will probably be a Dell, since those have the most options to assemble (at least in Belgium) and I'll need to have a dual-boot Linux/Windows by then anyways.... See More
