People like making this claim, but whenever I price systems at Dell or HP or Lenovo, the prices are comparable to Apple for similarly spec'd machines.
If you think buying spare parts off of Ali Express, and grabbing some MS Windows key for cheap somewhere, and slapping it all together, and think you are saving money, then you are only looking at the short term. First off, most people will not do that. Secondly, you are on your own, without any tech support.
Apple doesn't do tech support outside of the 1 year of Apple Care unless you live in a country that enforces consumer law rights anyway, or "right to repair" like the European Union zone countries or Australia.
And even then Tim Cook's Apple is more interested in selling Burberry handbag accessories than computers these days.
Just look at the M2 Mac Pro that's supposedly aimed at video, audio engineers, and 3D design.... Inside of the walled garden you can't even put a video card in that stupid box, and secondly unless you are on a short list of supported hardware, there is nothing available for audio engineers, the PCI-E slots are inherently useless.
And where the covers used to be for upgradable parts such as RAM chips there is nothing left but heat syncs.
If it weren't for the fact PC laptop components are stuck in the year 2008 in terms of heat vs power draw, there wouldn't be a single reason to use a Mac other than the OS. Which, while I like it, has even more limited hardware support than Linux or BSD these days as its two main competitors
And if it were for the fact Photoshop ran on Linux, or there was a decent video editor for Linux I would have opted out years ago.
Oh yeah, hardware support.... go to an Idiot Bar (where the supposed geniuses are) and ask why they wouldn't repair a top case issue with my MacBook because I'm not prissy and fastidious about the way a tool is supposed to look in terms of cleanliness where there is a clear hardware design fault that is known about these very Macs I am speaking of including the M1 and M2 Macbook Pro which they tell you to clean with compressed air rather than admiring its a design fault.
Apple is brilliant my ass.
If your MacBook (2015 and later) or MacBook Pro (2016 and later) has an unresponsive key, or a key that feels different than the other keys when you press it, follow these steps to clean the keyboard with compressed air.

When a $3000 laptop in Australia can be killed by dust there are even more significant issues going on and my current views by now are far from isolated.
