Uh, yes! There are stacks of websites out there dedicated to doing such a thing. You can even theme Windows to look a lot like OS X.
Not only can you theme and customise Windows to your heart's content, you can also do the same thing with the hardware. You have a ridiculous amount of choice when it comes to Windows hardware- high end performance powerhouses, sleek, svelte compact basic PCs, laptops of all sizes- you can even build your own! Isn't that what you advocate? Choice? How you can advocate the use of OS X when it limits your choices compared to what the competition offers?
Windows also offers more flexibility in the software it can run- if I want to run ancient DOS programs or Windows 3.1, 95 or 98 programs, Windows 7 will let me. OS 7, 8, 9 or even PPC versions of OS X software on Mountain Lion? No chance. Shouldn't I be able to run the software I want, rather than have Apple tell me it's obsolete?
That's great that you can admit OS X is inferior compared to Windows when it comes to customisation, however, when considering your advocacy for choice, shouldn't you consider Windows inferior to OS X in many other ways?
(For the record, I use both OS X and Windows on a regular basis. I think they're both great and appreciate both for what they are. I slightly prefer Windows for the huge variety of software available. I don't really care about customisation of either my desktop or mobile OS, I know a few people who do, however, and they greatly prefer Android and Windows for that reason. I do like tinkering with PC hardware though.
