Ahh, yes, the mac vs pc argument. The war of computer religion that makes nikon vs canon mild in comparison.
Both sides lie to get their product seem like its better.
From my side of things I tend to switch back and forth. I am in my late 30s, yet being a long time geek, have been using computers for just about 30 years now. I'm a computer programmer, a photopgrapher, a big time linux-head. In the early days of Mac, i hated it. Their networking sucked, and their hardware just couldnt keep up with what they wanted to do. I was clearly a PC guy (even if i disliked lots of things about windows). But in those days, Macs had all the good design software. Simply put, if you wanted design, you went mac (assuming you couldnt afford a high end graphics unix workstation).
Now a days, software is pretty much available on both, although PCs still have the market for some corporate work related software (there are still some VPNs that only support PCs unfortunately), and if you want to build it yourself, you are probably going to get better hardware for the same price point on a PC. That said, when you get OS X, you dont have to worry as much about viruses (but that could change as more and more people use Macs). Upgrading PCs piecemail is much easier than doing so on Macs (unless your talking laptops, then you are stuck regardless), but OS X comes with more tools that are better for starting out.
OS X is unix, and you can do a lot with it, but its also a crappy unix. (one of the most insecure ones out there, so if you ever plan to do any webserver hosting or anything like that, dont run OS X, it also has some major flaws, which is ironic that the free unixes out there are better than a billion dollar company's)
PC Laptops do go more than 8GB ram, so if you want to do a lot of ram/cpu editting and use a laptop, you might want a pc, as long as you realize you have to get everything you want yourself.
Personally, I think im going with a PC for my next laptop, but going with a powermac for my next tower.
at this point i really think each side has its pros and cons.
