First of all, what do you mean by finding data from an ass? Weird practice, unhealthy and disgusting.Nothing in that is specific to the Mac... And you want to eliminate some "disposable mac" but keep the "disposablepc" in your comparaison... Why is that. A bit dishonest no?
I have a park of 25,000 PCs at work. We replace the desktop every five years to keep abreast of the advance in technology. 95% of those never needed any hardware replacement in their life and are still quite usable. We give them to a non profit company that employs handiccaped people so they can be resold. And those are cheap "business" computers from HP and dell, not their performance, better build model.
I don't know from what ass you got your data that Mac last longer or are better built. Have you even open one up and see what it's inside? They're not special "apple" only components. They are the same exact parts that every body else use.
Have fun with those 25k PCs. A company driven IT policy is not the same as a personal computer use policy.
I am being dishonest? because you make an assumption about disposable macs then suddenly I'm saying the PCs are disposables? You can repair PCs easily than any Mac. Many of the Macs nowadays are disposable once they fail, however their failure rate is lower in my personal experience, that is my actual data.
