Let's break down your post real quick now.
Hardware differences that DO justify the cost?
A glass trackpad somehow justifies the cost of the system when the hardware is half of what you get with a PC? No thanks.
The car analogy fails because, again, a BMW is made from higher quality components than a Ford, and built by more highly trained workers. The BMW does not have "some" higher quality components, or a "handful" of higher quality components, it is ALL better. The MacBook (and "Pro") have the same chipsets, processors, HDDs, RAM, optical drives, screens, keyboard material, etc. found in PCs.
Now let's move on to the rest of your post.
High end unibody? Hardly high end. The only "strong" part about it is the middle piece, but you can find pictures on this forum that prove its nowhere near as strong as its claimed to be. The top and bottom aluminum covering the components and the LCD are still very soft and very easily damaged. Like I explained in my post, I've seen plastic PCs take a hit and do damage to the piece that was hit while taking no damage themselves, while I've seen the unibody Macs take a hit and become deformed. The unibody is a gimmick.
The glass trackpad is also a gimmick. Multi-touch is completely useless in the real world and, again, can't make up for the OSes lack of overall real functionality. Give me a REAL trackpad with REAL buttons.
MagSafe is a fire hazard. The cord breaks down with time and the wire becomes exposed and that creates a fire hazard. Don't believe me? Google it. I'll take an "old fashioned" power adapter any day because I know the cord won't break down with time and catch fire.
The OS? Trust me, you don't want to get me started on how incapable OS X is compared to Windows. Windows Vista and Windows 7 are better than Leopard, plain and simple. In some ways, like video playback, Windows XP is better than OS X as well.
Real world 8 hour battery life? Well, thats Apple's claim for the 17" MacBook "Pro". The smaller units clock in at 7 hours supposedly. No other laptops have this? Thats funny, because my 15.4" HP with dedicated graphics has had a 12 cell battery for the better portion of this last year. Guess how long that lasts? Yup, 7 hours REAL WORLD. And guess what? ITS USER REPLACEABLE.
So let's go back to basics here. A MacBook "Pro" either gives you much less hardware for the same price, or is priced double what it should be. For a few dollars more than the cheapest MacBook "Pro" (yes I deliberately use ""), you get faster processor, double the memory, faster and larger HDD, dual GPUs, more standard connectivity like eSATA, HDMI with audio, VGA, full size ExpressCard, multi-card readers, etc. A larger screen system for the same price will run circles around even the most expensive MacBook "Pro" and come with all of those features plus others like blu-ray.
Let's put it this way. An equally priced or half price PC will get you features that actually matter in the real world. Not any of these things that just add to the looks, like a glass trackpad or a fire hazard for a power cord. But REAL functionality, REAL connectivity and things that will help you use your computer IN THE REAL WORLD. PCs are NOT vanity computers like Macs, they are meant to be used and connected.
Wow, what a bunch of nonsense!
I've used Vista and Leopard on the same hardware, and Vista has ALWAYS felt faster on my Macs than Leopard. Always.
How is Windows Media Center lacking compared to Apple TV?
Windows Media Center's UI is light years ahead of Apple TV/Front Row. Not only that, but Windows Media Center supports multiple HDTV tuners, so you can record all of your favorite shows in high definition, it supports blu-ray playback so you can watch your favorite movies at twice the resolution and up to 10 times the bitrate of Apple TV "high definition", Windows + Windows Media Center also supports 8 channel LPCM over HDMI, so you get lossless or uncompressed audio along with that much better picture. No compressed lower than DVD audio like Apple TV.
That is complete and utter BS that was never true, and that article was written by an Apple fan. You want to try to tell me that an iMac that costs $1,000 more than a desktop PC with a quadcore processor running at a higher clock speed with a faster GPU than currently available for any Mac will run Windows better? I don't think so.
The only reason Windows runs seemingly so good on Macs is because OS X itself runs so bad
PCs are crap, eh? Thats why I can buy a PC for $2,000 less than the Mac Pro that has 90% of the processing power, probably 10x the GPU power, and is more capable in ways such as being able to play my blu-ray movies WITH HD audio?
"Just works"? Not quite. I haven't seen a BSOD since 2001. However, Tiger and Leopard have brought back the Windows 95 days of full system crashes where the entire system locks up and the computer has to be force shut down.
