I worked for two months this summer in our local big computer store (the sell Apple's as well) - I was their "Mac guy".
It always amazed me how people decided between Mac and PC.
This particular case was choosing between a pink Sony Vaio and white MacBook 2.16:
(them) - Oh it so pretty! (on Mac)
(them) - Hmm... but its 50$ more expensive...
(me) - Macs' main advantage over PCs is their operating system
(me) - also, this MacBook model although 50$ more is thinner, has a much faster processor, is lighter, has MUCH better battery life, MagSafe port, very comfortable and big trackpad, much better design and port locations, etc etc...
(them) - oh, but its 50$ more.... We'll take Sony!
LOL
Remember, NEVER compare hardware specs when choosing between Mac and PC - its the OS that's most important. Even if I get offered a super-mega-ultra PC with SLI 8800 GeForce and Core 2 Quad or a much slower Mac (like iMac, even CoreDuo) - I'd take the Mac without ANY doubt. Thats because I can't stand Windows. Its the WORST OS in the world, I dont get how people use it - they probably dont know about the alternatives!
Most of the time when you're at your computer you hardly notice the hardware you have, but you ALWAYS see the operating system. Thats why I try to avoid PCs as much as possible. If the computer isnt working as it should - 99% its because of software.
