My wife's macbook died. Multiple times. Several were hard drive failures. We replaced, with Apple-nazi sanctioned hardware. The final death was when the graphics card stopped working. Could get a framebuffer on it. But anything more intensive? nope. Thing said 'Newp!' So I said 'good-riddance'.

You can like whatever hardware you want. As for me and my house? I don't run Apple crap.
Too much headache. Too much engineered obsolescence. Too much money for what it's worth.
Even with the "better hardware" rationale for fanboys paying out every time a new phone comes out which only improves slightly on a camera, or better, adds a feature that android has had for years.

I wouldn't want to do any serious work on your old macs that are ancient. Have you done any vulnerability scans on them? "Might want to look into that" ~Tony Stark, as he bonks the head of the bad guy in Iron Man I.

Anyways, I'm not going to change your mind, and this conversation grows ancient. Like your macs.
