So I just ordered the rMBP and have been happy with my order...until I thought about the possibility of have some first gen issues with it (immediate or down the line). My concern is that this is my primary and only computer at the moment. I cannot afford to be out of a computer for a week or 2 if any repairs are needed. It would severly strain me. I know it's a first gen and to my knowledge Apple has manufactured a couple parts themselves (though I may be wrong). They're also fairly new s nobody has had them for all too long. What do you think the chances are of part failure? And aside from cost...what do you think the turn around would be...would it be longer than normal being that tehy're more complex machines? Does anyone know if there's a way to get a loaner? Or am I just not making the best decision with the rMBP if this is my only machine.
