Well, look upon it this way: If Mac was the dominant machine, you would have the same media bias as you have against PCs and Microsoft/Windows now. The geeks claim we should all install Linux and all our troubles will be over. If we're geeks.
IMHO we will get a machine within 5-10 years that will be able to handle most popular operating systems at the same time, and then some. Mac's Boot Camp is only an indication of what's to come. I've previously stated that I grew up with MS-DOS and later Windows. I'm not a geek, but when something
very rarely is wrong with the system, I can go in under the surface and understand what's wrong, maybe even fix it on my own. As for security, IMHO it's all up to what protection you have. (If that ain't an invitation for double entendres...) I run one single protection program on all my machines, both at home and professionally, and I haven't had a breach since I got it. You have to pay, but people still seems to think that there is something like a free lunch, and wants to welch on security by expecting freeware to do the job. The most hillarious thing I know is people running Outlook etc on Macs going "but...but... I have a Mac! There's no viruses for Macs!"
