Reading the posts of some X86-happy people makes me quite angry.
I'm not going to argue with anyone about who has more marketshare or what kind of car company sells the most cars in Germany, because I know that I will not change their mind and eventually I will get so worked up that I'll start posting in daemonic rage and end up getting banned from MacRumours forums
I will say this, though: Apple makes great machines. They are innovative, fast, efficient, and beautiful. PCs make for great computers as well. I own a custom built AMD machine which works great (not AS well as my Mac, of course). Sure, they may be more expensive than a crappy, $400 Gateway or Dell, but you can't compare the two because they aren't aimed towards the same market.
Sure, you may not be able to have every single app made for a PC on a Mac, but who cares? Mac apps are so much better. Look at iTunes, iPhoto, iDVD, iMovie, and Garageband. Tell me the programs for a PC that are better than iLife, free, AND work seamlessly together. I have every program that I need for my Mac, and I never have to worry about getting viruses.
Apple laptops are the best. There is no argument for this. Every single PC laptop I have seen is next to horrible. A PC laptop is 7+ lbs, 1.5" + thick, uglier than my rear-end, slow, and $2000 +. Mac laptops are 1.35", 1.18", 1.1", and 1" thin, less than 6.9lbs, incredibly good looking and sleek, and while they may be more expensive, you get what you pay for.
So...uhh...(Quick, think of something smart to say to summarize your points!)...42 + 2 = 44!
