One positive of the recent slowdown and doom&gloom analysis that followed is that lofty, unrealistic expectations of unicorn world-changing-devices-every-second-year have been nuked down to reality.
You're completely missing the point. They aren't even updating the specs. They're using 3-year-old CPUs, no proper video card, no ports, etc. It doesn't take much effort to refresh the specs. This is the richest company, and they can't afford to put a modern CPU in a MacMini. I'm an engineer and I understand how hard design is, but even noname Chinese brands are updated regularly.
