I'd have released slower clocked parts and EOL'd the PI's quickly so they fade into memory along with the Apple Lisa, split keyboards, Cyrix CPU's, and one button mouse.
Lets add diasy wheel printers because those things drove me nuts.
I don't know about that. They have already EOL'd the 9x00 series, and the 9750/9850/9950 series is actually very good, comparable enough to the Q6600. They have already dropped to the $150 range, and hardware requirements haven't really gone up tremendously over the past couple of years. There aren't a lot of applications out there that make use of all 4 cores yet, so it still has some future-proofing capacity. You could pick one of these up and not need an upgrade for 3-4 years, which is pretty good for the price.
