Come back in 10 years and try to say that again.
iFixit exists because at a certain period in time between humongous PCs with MANY discrete replaceable elements (like the original "portable" compaq) and all in one devices, there is/was a place for them. I can remember going to radio shack with my father to plug the vacuum tubes we pulled out of the TV into a test device to figure out which one had gone bad and causing problems. iFixit's rants that Apple is making it hard for them is the equivalent of radio shack bitching on how those new transistorized TV's were bad for the environment because you couldn't as easily test for a failed transistor.
People didn't want easily repairable (but flaky) TV's, they wanted something that was reliable for the period of time they were going to use them. Getting rid of the heat/weight/connector issues by integrating has been going on for decades.
Same thing now with phones, tablets & even laptops (as my son's macbook proves) & the complaints of the radio shacks of the world whining that things should stay the same so that they can continue to make a buck are irrelevant.
