For me the only barrier has been Parallels VM support. I use an XP bookkeeping program from the late 90's that I own - no monthly licensing fees. VM's are one way to preserve your reliance on old out dated software that is fit for purpose. I understand this issue is resolved so the future is more encouraging on that issue. I bought the intel 2018 mini in December 2019, thinking it was time to prepare for the end of my mid-2010 iMac I7 and see if the reported improvements in Photos were of value. I thought back to my first Apple experience which was a 2007 mini running Snow Leopard. I figured if I could work in those restrictive parameters, why not go minimal on the mini. I chose the i3 8GBRAM, 128GBSSD, with the 10GB ethernet. I am not a power user by any means, so this little box has been outstanding. The only deficiency I have had is the system SSD is a bit small to accommodate major swapping. This happened only once when I was converting a large number of tiff photos to jpg. It has forced me to keep a lot of data on an external SSD, which is where it should be any way. In my good old, "cringe" OS/2 life, it was a simple configuration to locate the swap file away from the system drive. Since the Big Sur 11.3.1 update, I have been afflicted with the intermittent HDMI video issues. Fortunately I had purchased a CLDAY Thunderbolt 3 to HDMI cable and was able to switch over. Tomorrow, the mini goes to the Genius Bar for assessment. This is a known problem, so if you jump make sure you have a monitor cable that will connect to Thunderbolt/USB4.
