Two points:
- It's far from ancient hardware. If you want the newest hardware, you should buy Dell or HP and shut up.
- Older, understood hardware is more reliable. It's no coincidence, that the Curiosity rover which landed 2012 on Mars uses an RAD750 CPU. RAD750 is a hardened version of the PowerPC 750 CPU, also known as G3. You should recognizes that. And yes, that's ancient.
What seems "ancient", is a consequence of Intel announcing some new architecture and then not delivering. It's hardly Apple's fault.
A design process that values reliability over raw power doesn't switch crucial hardware two weeks before release date, because some guys want 10% more processing power.
Yes, I want every percent of performance, I can get, when I throw NeatVideo on a FullHD clip. But and this is a big BUT, more than that I need a system that doesn't constantly crashes on me. If the system crashes 50% faster, I still have 0% progress.
