Because what would he complain about now?
The update is terrible.
The update is terrible, I agree. But whining about a wait for a year and a half is just ridiculous. I needed a new Mac Pro a year and a half ago, and I bought it. It's still a very powerful computer, and with upgrades I'll make it last for at least 3-4 more years. At least.
I don't think the buyers guide should class this as an update...
