Apple computers inners are made of standard components. Its laptops are based around the same price as gaming laptops ( but without the graphics - and less hard disc space ).
In 2013 Apple is a consumer brand. Not a luxury brand.
Your statement demonstrates that Apple IS a luxury brand. Eventually you mention that you think apple is "high end" as opposed to "luxury", but the difference between these is often merely semantical.
But, if Apple really was "high end", would they merely have standard internal components? Or would they have "high end" components?
Apple charges you a premium for primarily 2 things (3 if you count customer service), and those things are 1) the user experience from their OS and software, and 2) the user experience from the physical design of the product (aluminum bodies, attractive and often thin designs, the nice material of the trackpad, etc.).
Some of these things are entirely unnecessary (e.g. making the computer case out of a unibody block of aluminium), and everyone knows that Apple's prices are far higher than any other computer manufacturer. That makes them a luxury brand. Pretty simple. The phones seem less "luxurious" because most people buy them at a subsidy.
And by the way, you complained of waiting 2 weeks for a logic board and battery replacement... while that's slower than usual for Apple, that's still WAY faster than the service you would get from any other computer manufacturer.
Wether they are "high end" or "luxury" is largely a matter of semantics, which is quite subjective, but if you apply general definitions of these terms, everyone knows that Apple qualifies the most out of any consumer electronics company as high end or luxury. Yes there are a few niche computer makers that make fancy computers that cost $10000 but they are niche products.
A couple of definitions of luxury, from the first google search result:
1. Something inessential but conducive to pleasure and comfort.
2. Something expensive or hard to obtain.
That's Apple.
The second point can vary in it's relevance based on the income of the consumer, but if you look at the median or mode of incomes in say America, it readily explains the small marketshare of Apple computers.
