This is a thread where you can give me good, rational advice...that I can ignore and blow $2500 on whatever iMac refresh happens this Spring. Currently, I have an early-2009 iMac, a 2.9GHz C2D CPU. It's slow. It can't be upgraded to the latest macOS. Did I mention it's slow? I could upgrade the slow spinny drive to an SSD for $150 and a weekend's effort and likely improve its slowness a lot. But that wouldn't fix its lack of USB 3, and unsupported-ness by current macOS. Springboarding from my prior thread How to buy a "new" Mac affordably?, I concluded that buying an older iMac and upgrading it was unsatisfying. I'd sacrifice USB 3 and retina. And while my needs are modest, I have techno lust for more than I need. I've done the annual budget. I've got money allocated for a new computer.
