Because Apple's end game has always been to turn the computer into an appliance. This is not a new development. This strategy failed for decades until the PC became ubiquitous and mass market. When computers are no longer limited to the tech elite, Apple's strategy of dumb appliances make much more sense. It's automatic verus manual transmission. As for me, I've never upgraded a computer in my life beyond adding RAM, because in 4-years time, my motherboard inevitably becomes incompatible with everything in the market anyway. In order to upgrade, I'd have to buy a new motherboard. So in that case, if I end up having to build/buy a new computer every four years anyway, is upgrading really that important? I don't upgrade my microwave. I don't upgrade my toaster.
