That is true, there is more to a computer than just the parts. However, when you bring this argument up, it shows how Macs fail in an even greater sense.
Didnt feel like quoting your rebuttal, You must be a lawyer because you are adept at twisting my arguments to suit your points.. Touche to you on that.
You might be correct about the stability (or lack thereof) of OSX, I dont own one so I might be in for a rude awakening.
Ok lets start with your Points
1. Design:
You claim that "The UniBody systems are no more than HP's old two tone and glass design combined with Sony's keyboard in a metal frame". Wow, you are a bit clueless. That is like saying "A pretty person with a nice body is no more than an ugly person with a nice face" or that a pair of designer jeans is no more than "$30 walmart jeans with the details of a pair of diesel jeans and the cut of a pair of dior jeans". An to compare HP design with apple shows how little of a premium you place on design. A Mac computer is a piece of artwork, a functional blend of Aluminum and glass, fused together in an almost seamless manner. The designs are the epitome of understated elegance. No cheap tacky extra buttons, or unsightly ports, or annoying led's. I realize that design is subjective, but all the design aficionados all love (and own Macs). Design has nothing to do with durability so throwing in arguments about how plastic is more durable than Aluminum is a moot point. That is not Apple's fault, this fact is unique to the properties of Plastic vs. Aluminum. Apple likely picked Aluminum for aesthetics, stability and low weights vs. Plastic. If you didnt like the Aluminum perhaps you should have bought a HP or Sony laptop and hacked it to run OSX
2. My Car analogy between Macs and PC's
You claim that "The difference between a Porsche and a Nissan, or a Honda and a BMW, is much different than the difference between a Mac and a PC. BMW and Porsches are built much better. Everything from the various components in the engines, to the seats, to even the mountain brackets for the seats are all of MUCH higher quality than a Nissan or Honda."
Definately not TRUE !!!! While BMW's are engineered more precisely than Honda's and Nissans, they are not better built. Almost all German luxury cars start rattling past 50K miles (My last car was an Audi A4 and my dad has always owned BMW's) but most of their non luxury japanese counterparts dont suffer from this condition. BMW's are more expensive because they use less to accomplish more and they perform and handle much better than their non luxury peers. Yes they use more expensive materials, but their overall quality on all levels is worse than the Toyotas, Hondas, and Nissans...
However, I do agree that you can shoot a lot of holes in my argument so I tip my hat to you in this regard. I was just trying to emphasize the point that Speed and Specs DO NOT make a system.
You claim that specs mean that something is more capable. That is incorrect. Most of the HTC phones that sport windows mobile have far better specs than an iphone. However the iphone wipes the floor with them because of its far more intuitive software. A 296 HP .96g Porsche cayman is faster than a 337HP 1.01g Nissan 370z in both a straight line and around a track despite having less "Specs". Plus the 370z has more features (i.e better Nav system, Bluetooth, Rev matching trans... e.t.c) than the more expensive Porsche, but the Porsche is still the choice of the automotive enthusiast who CAN afford it. Yes I know there are a lot more reasons for this choice, but when it all comes down to it, the Nissan has more "Specs" but is still inferior. The Windows mobile phones have more specs but are still inferior. When will you people understand that above a certain point (and to most users) hardware means nothing. "Wow you can get a 2.96GHZ PC for cheaper than a MAC, and it comes with HDMI, 1TB hard drive, Blu-ray ... 6GB of RAM, 17" WSXGA scrreen and it costs $900", Look, I am not speaking for anyone but myself, but I dont need 1TB, or HDMI, I dont need Blu-ray on such a small screen (next thing you are going to be asking to 1080P on a 10" TV). I know Blu-ray always has better quality but I really dont care.. How much is good enough ??? I dont need the very best hardware. I just need hardware that is good enough. Right now I use the supplied Iphone earbuds to listen to music. Its quality is barely passable. I have owned countless other buds that have better sound quality (and cost more) but in the end I picked the apple ones because they are good enough. There is better but I dont care, this is good enough. Thats the reason why a lot of MAC users buy them. They have excellent software, a good and appealing user interface, killer design, less hassle, and their hardware is good enough (for most users). So there you have it....
