It looks like they're just trying to push people to buy new machines instead of upgrading the old ones, which is disappointing.
Or getting power users to buy the non-base models. I have a 2012 Mac Mini base model, and upgraded it to 16 GB RAM and a 256GB SSD for little cost. It should go without saying that I'll keep it for a while and probably double the SSD in some point in the future.
If Apple were just trying to get people to buy upgraded stuff from them, I'd understand. But they're not even doing that very well; the $699 configuration minis still come standard with a 5400 rpm spinning disk, for example, and SSDs and 16GB RAM are both considered "customized Macs" that you can't just walk into any Apple Store and buy.
