yeah, i mean what kind of geek do you have to be to unplug connectors that go in only one way, unscrew 4 screws holding the PSU in place, then reverse the operation to install the new one. 5 minutes of google or youtube would show even the dumbest of people how to do it.
I blame Apple personally. They've created a ridiculous perception that computers (to include smartphones) are mysterious devices that the average person not only cannot fathom, but has no business even trying to mess with. They offer 'Genius' support for farks sake. How can any Apple user not be insulted by that? 'Just bring it in, we're smarter than you! If you don't pay for us to plug things in, who knows what might happen to the universe?' If this was limited to the relative minority of people that actually use Apple computers it would be sad, but not so harmful. Unfortunately, with their massive phone and tablet user base, this mindset expands to encompass any device more sophisticated than a toaster.
