ok were all familier with it and until Thursday night i had never actively used a mac. (i got my new MacBook Thursday night.)
while the mac commercails are walking all over microsoft. they ave virtually no drop in sales. then of course there are the linux distro's. i dual booted fedora core for about a year. so since i have some form of experiance in each major operating system i will now present my pro's and cons for each. feel free to disagree on anything you wish.
Windows...
pros:
ok so i have been using windows since the only version out was 3.7 some mac look-alike version (very strange and i may have the version number wrong suffice to say it as one of the first few...) the great thing about windows is the fact that everyone develops for it....always. there are very few popular programs out there that don't have a vrsion that runs on windows.
cons:
every script kiddie on the planet has hacked a windows machine... or given it a virus etc... while the windows system is "closed kernal" there are still a plethora of thing you can do to protect yourself. the only bad thing is that YOU have to do it. and it is hard, confusing, and time consuming... then there is the whole restart required thing...
Mac...
pros:
ok so while most devs also produce for macs the problem is that the crackers i count on to crack the program then distribute it across limewire, bittorrent, etc. don't crack it for mac...(bastards...) so while legal programs are easy to come by the illegal route is harder. the open kernal is nice as well as the powerful unix commands. thr reduced number of viruses for the mac system means that you don't have to be as carfull with what porn sites you vist or what emails you open, a nice feature to be sure.
cons:
so the whole thing behind mac is the no more restarts, viruses, compatability problems, etc.... i would like to point out that every single one of those things still happen just no where near as often. like i said before the whole program thing.
linux...
Pros:
honestly i love linux it rules... i really went and tried to get a virus by downloading programs i knew to have tojans and the like i visited sites that i knew ere shady, the whole nine yards... end result no viruses no spyware.... i love that. the posibilities fr custimization are endless. learning how you can custimize it is a bit difficult of it isn't your first system and you have the habits of a mac or windows machine still polluting your mind. other than that everything is fast... damned fast.
cons:
there s really only one thing i can think of... nobody makes programs for linux.... NOBODY.... don't get me wrong that was an exsasuration (i butchered the spelling on that one

) there are a few good programs but the linix market is slow...
there you have it my very vauge opinions on the three major contenders. there are many more if you feel that your operating system kicks ass and it isn't here speak up. ill install it on my pc laptop and see how it lives up to my standards.
