You could and I believe still can, buy all the parts for a PC and build it yourself. Where are the entirely open, 100% user repairable, industry standard, kit laptops?
Excellent question, Greg! The answer is quite simple, and in the form of a question: Why buy an expensive kit when you can easily buy all the parts separately? Kits are for lazy people with too much disposable income and no Maker spirit. If you aren’t willing to painstakingly research each individual component, you might as well just sell your soul to the computer retail industrial complex. What good is owning a laptop if you can’t point to it as a marvel of your technical prowess? Or are you one of those people that wants something that “just works”, as if a functional computer is the end goal of all this? You don’t even write your own software do you?
My question now to you, Greg, is how do you even consider yourself a computer enthusiast?
