The Mini was never about paying less for a Mac. It is about choosing what your system has and what can change in the future.
Wow ok, I wish I had read this explanation a bit sooner. I bought an iMac in the end, it hasn’t arrived yet, however I know I won’t regret it since I don’t really need too much power (I’m also not a gamer), so as long as the GPU doesn’t fail I’m ok with the RP580X and the i5, my only regret is that I lose any kind of portability with this one. Nonetheless, if by the time I have to change computers again the mini is still around I will give it another chance. I really wanted to get that one but I didn’t have peripherals or eGPU and so on, so I thought it would be more convenient for me to chose the iMac in this moment.
Thank you for this insightful answer, I’m sure it will help others that my have the same dilemma about what computer to get. A mini with the right tools is a great machine.
