The way I see it, everyone thinks Mac's are some kind of high-end specialty PC when in reality the opposite is probably closer. There are literally hundreds of thousands if not millions of part permutations you can base your PC off of and there is so much competition PC's can afford to sell for less.
The point of a PC is to be able to mod it specifically to the task at hand. For example: my rig is going to be a gaming rig although I'm also concerned about form factor (very small, shoe box size) so I can use a low profile GPU or a single slot GPU. I need a smaller motherboard so I can use a mini-itx motherboard (6.7'' x 6.7'' or 17 cm x 17 cm). If I need a low profile heatsink for my CPU I can find one that is exactly the right dimensions. I need a smaller optical drive so I can use a slot loading drive. I need a small hard drive so I can use 2.5'' drive instead of a 3.5'' drive. And since ATX PSU's are big I can use a mini-itx PSU for the motherboard and GPU PSU for the GPU.
And if you want to go for the awe factor I can chrome my PC or get an industrial strength paint job (falcon northwest for example). I can even get liquid cooling or if I'm into over-clocking I can get LN2 (Liquid Nitrogen for those not in the know). I can get 6 hard drives, or SSD's, Sound Cards, Network Cards, Physics Cards (now on NVIDIA GPU's), Quad-SLI/FIRE (4 GPU's) or dual CPU's.
And if you're into modding. There are people who live and die by modding PC's. It's akin to an art form for many of them.
And all those people who say Apple doesn't copy windows, it goes both ways. PC's have had slates for over a decade. The iPad is nothing new, it's actually a step backwards. PC's also have tablets, all in one PCs, netbooks/nettops, tabletop PC's, etc.; all products which Apple doesn't have an equivalent for.
Furthermore, if Microsoft optimized it's OS for just one platform like Apple does it would be awesomely fast despite hardware. You want proof look up something called the XBOX 360, you may have heard of it before. If not the guys over at red v. blue have a machinima primer on how to use the internet and the differences between the internet and real life.
The point there is nothing a Mac can offer me that would convince me to buy one. My job here is to make your realize how pointless buying one is and save you money.
If you have to have OS X build a PC (buy if you must, more expensive than building but still cheaper than any Apple product) and install OS X.
Obviously I can't make up your mind for you, but just something to think about.
