I think the OSX interface is much more intuitive and offers great media applications, particularly Final Cut Pro, if you're into amateur film making.
If you can slap together your own machine at a reasonable price that can accommodate OSX, then all the power to you. I don't mind Apple as an OS-maker, I just despise them as a computer-maker, because their computers are so overpriced. It's the only way for them to really make any sort of profit, by limiting their OS to their own computers. What I hate the most is that they tout Macs as being technologically superior to PCs... HA!
