I FUCKING hate Microsoft and Windows
I hate the Microsoft Windows architecture so very badly. Why do I say this you might ask? Well, there are so many problems with the Windows architecture. Plus, they keep changing the name of the next release of Windows. Mac OS X has a LOT of stability and a lot of the features that Microsoft is copying, and more. And, Macintosh computers are always a bit more secure than their PC brethren. Plus, Microsoft has a very closed source coming library called DirectX. For the uninitiated, it makes it hell for game developers to port their applications over from Windows to Mac or Linux.
I think I agree with Bertrand Serlet (Sr. VP - Software Engineering, Apple Computers) on his comments about Windows in general and Windows Vista made at WWDC 2006. There are many things that you would see as stolen from Apple. The local search (stolen from Spotlight), IE 7 RSS, Windows Mail and Windows Calendar have features stolen from Mac OS X. Underneath it all though, it is still Windows. It still has the Registry, it is still DLL hell and it has terribly aggressive Digital Rights Management.
