*sigh* I tried to resist posting on this thread, but there is just too much ignorance and misinformation I could not resist.
Are there any viruses for OS X?
NO, there are NO known viruses in the wild for OS X at all. Yes, hackers are trying to exploit it because they can get the bragging rights for the first wide spread virus. It has nothing to do with market share at this point because there are plenty of hackers who also hate apple and think they are arrogant, after all Apple is a large company just like Microsoft, Dell, IBM, so on and so forth. It has to do with Unix POSIX permissions that would not allow anything to run automatically with out authentication, why do you think Vista finally started creating an Admin and non admin accounts? It is because it is a security liability.
Are Macs over priced?
No, not at all. When you go to a Porsche dealer, you pay Porsche prices. They are sleek (1" thick) and have features no other laptop has like Ambient light senor, sudden motion sensor, FW800, ABGN wireless, blue tooth, gigabit ethernet, camera, 2gigs of ram standard (on the pro laptops), back lit keyboard, so on and so forth, and that is just the hardware. Out of the box they can also record and master digital audio, author DVDs, edit video, manage and maintain all your digital pictures. Out of the box the Mac offers way more features than any PC, and it is all streamlined and native. WMP still can't even play a DVD out of the box with out some codec you need to download. You get what you pay for period. Sure there could be a Ford car that has similar specs to a Porsche, but it will not have all those features a Porsche has. Can your 1200 dollar PC laptop which is similar spec'd to a 1999 dollar macbook pro do everything the macbook pro can out of the box? No, it can't and by the time you add all the software costs and extra features you easily have bought yourself the macbook pro. The problem is that Macs don't really have any midranged systems, they are all high end, and you can't really buy a barebones Mac at all. So, if you are a very simple user and would never need any of the features and have no preference over mac or PC, then get a PC because it will in the end be more cost effective.
I have owned 3 Apple laptops and probably 6 or 7 PC laptops my entire life, and I also manage and repair just about every laptop you can think of, and in my personal experience the Macbook Pro is the best damned laptop I have ever owned.
Also, Macs can run windows, so if you really need to run windows for an application or two you can.
