That is a noble enough goal, but IMO, the 2012 model that it replaced was much better, in addition to being user-upgradeable. Geekbench scores are a little better on the 2012 model. Apple made a big deal of dropping the price to $500 from $600 for the base 2012 model. But at the point when the 2014 Mini was introduced, the street price of the 2012 Mini was $550. So for a $50 savings you got a slower machine that was less upgradeable.
Now I will admit, it's not all bad. The 2014 model has 802.11ac wifi which is much faster than the 2012. That probably won't be noticeable unless you are using shared disks on a local network and have a compatible router though. And the 2014 has a better graphics system. But I think it's fair to say the 2014 was a disappointment to many people.
At the high end of the Mini line, it's even worse IMO. I just got a used 2012 top spec quad core Mini. It is 50% faster than the current top of the line 2014 Mini….
I agree with everything you said, but I was answering a very specific question and not trying to imply that the 2014 is better.
