Um, wow. You let your personal opinion leak all over that one.
First of all how can you say that a mac is not "more safe" (FYI it's safer) from viruses then a pc? All you have to do is look at the data to realize that's not true. I always say there's no point in getting in an arguement when the data can do the talking. 200,000 viruses for pc and noe for mac (other then proof of concepts). so how can it possibly be 'not more safe'.
Most businesses run windows pc's. They have to secure them. I;m writing from a Canadian Gov. windows 2000 pc right now. The whole gov uses windows. Doesn't mean it's more secure. The company (gov in this case) is the one securing the system, not microsoft. They have high farewall and virus protocals in place. If more large businesses used macs then yeah they would have to implement their own firewall solutions. This is simply for data security, not because they have a plethora of viruses to worry
about.
About the software... Yup, there is less for Mac. That is true. And the reason I would NEVER consider a mac in the past. Never thought I would either. Bootcamp changed all of that. Now you have the best of both worlds. Mac security and productivity with windows gaming and compatibility. So your point about being able to do the "exact same editing" on a pc..nope. You have all the options you have for windows on a Mac now PLUS you can use the mac options (namely final cut) and work in a better environment (OS X).  That alone is worth the extra cost...but not the only reason...
You do pay for the brand.. of course. But it's not just because of the brand. You can't slap an apple sticker on a dell and call it an apple. People love the astectics of a mac. Its minamilistic, functional, leading edge, innovative. Why would you buy an ugly ass windows only laptop with a bunch of junk you dont need..ugh, a serial port? who the fuck wants that? And a mac is just so low profile.. 1" thick, 5.6lbs for a 1" MBP compared to about 6.5 for any windoze pc. Plus its so innovative.. slot load dvd, isight, express card, wireless N (draft), firewire 800 (best option for bus powered external available), digital + optical audio in 1 3.5mm minijack (brilliant), all aluminum (MBP), magnetic power adapter (brilliant), no junk I don't need (serial port, outdated pc card,etc.) Plus it has everything you want built in (mic, camera, bluetooth, wifi (N).
Now add in student discounts (ADC if you're a college student).  And you have a mac that is about the same cost (sometimes even better speced) then an ugly windoze pc that you can dual boot and run every program on earth.
