I'm going to run into trouble at work in the next month or two as my machine has reached the end of it's support cycle (AppleCare) and IT doesn't typically like to have main production computers without instant support (hence how I lost my 2010 tower). ...
It really is insane that Apple hasn't updated the nMP for longer than the maximum 3-year AppleCare extended warranty. So if you wanted to get a new machine that IS covered by warranty, you'd have to buy the same machine again at the same price you paid for it over 3 years ago. Yeah, I know there are all kinds of excuses for the delay (Intel road map, whatever). But no speed bumps? No price cuts? In over 3 years?
Apple is clearly not invested in the MP. That's a strong message that we shouldn't be either.
