I understand what you're getting at, and having this discussion on Mac forum is pretty funny. The way I justify this is again by looking at the facts and what you get for paying the "apple tax"
Since PCs and Macs are made with the same hardware these days, the internals obviously aren't a selling point. In my point of view, I gain the slim form-factor, and the ability to use OS X with no fuss. Especially being in the music industry, being able to use Logic is great. Although Pro Tools is ubiquitous, Logic is gaining a foot-hold. Available software aside, OS X is based on Unix, and for the time being has less security threats than Windows does.
What do you get for paying the "Bose tax"? It seems to me that you get inferior build quality, inferior materials and components and ultimately inferior sound for the price.
Fun stuff

So.. to your logic your paying for "slim form factor" and hassle free operation. Funny thing I purchased the Bose because I like the "small form factor speakers" to keep my desk clean and tidy. I love the volume control and touch pad mute they have for easy operation as well.
Sound quality (while I do think they sound fine for the price and for a computer speaker) is not always on the top of everyone's list. Clearly the performance of internal parts on our Mac books is not top of the line, we know this when buying a Mac. Anyone can buy a faster, larger laptop for less etc... We purchased it for reasons just like you state.
To your last sentence, I could easily show you several hundred threads showing Apple's inferior build quality (hinges breaking, cracks in the iPhone cases, Plastic MB cracks, LED screens with lines, light bleeds etc..) the list goes on and on. Why do these problems occur? Poor QA, inferior materials used, poor build quality.
I get what your saying but it's all pointless when were all using a product with the "potential" for the same problems. My personal history with Bose products has been fine, nothing has fell apart, they served their purpose well.
In closing.. I may not know jack about sound science/quality, I do know what sounds good to me as I'm sure everyone here does. The one thing I do know is I have enough common sense to know for every negative there is a posiitve. That whole pesky Yin/Yang thing.

The internet is full of biased opinions on every topic and for every site you may find to back your opinion someone else can find 10 to back theirs

I've always found it best to look at all sides of a situation vs thinking I am 100% right as that is rarely true for anyone, the older you get the more sense that will make
