My experience with Apples is that they have heat problems, which would explain why so many of my Apple-owning friends have spent lots of quality time with AppleCare getting their motherboards and hard drives replaced.
If you want a skinny, sexy (whatever) laptop to go with your skinny, sexy cell phone, all in the hope of convincing complete strangers that you have a skinny, sexy girlfriend at home, well then, by all means, knock yourself out. Or you could by a Sony - they've been copying Apple's design for years, and they've got some of the best looking displays I've seen as a bonus.
Or if you must make some sort of gesture of defiance against Microsoft, just suck it up and go Linux.
For the record, those Windows Guy vs. Apple Dude commercials? I really want to punch that little hipster shit in the head. That's the kind of guy who should have been beat up more when he was in school.
EDIT: And? iTunes blows toads. It's bad enough that I am forced to use QuickTime (which I've seen hijack all sorts of functions as it goes in) to view porn clips, er, I mean, movie trailers, but in order to use their shitty little media plugin, I have to install the entire iTunes program, which then tries to hijack my music library? Let's see, proprietary bloatware that hijacks your system and installs stuff you never asked for and don't want - isn't that what the Apple-heads used to say about Microsoft? I have had to manually pick kecked-up QuickTime and iTunes installs out of more people's systems that I can count. iTunes is, quite literally, the reason I will never use an iPod. The Creative Zen player I got several years ago is still working perfectly, thanks.
