That depends.
If your workflow and livelihood depends on those particular hardware form factors/products then yes, it's time to move on. That's assuming of course you can migrate your workflow and tools to Linux or Windows. The small-form factor and workstation categories are very well represented by PC makers.
If however, your needs can be serviced by a different Mac, then the less painful transition is to buy one of the (seemingly few) Macs Apple is still interested in maintaining.
I'm curious, as a lawyer what are your computing needs like? A friend of mine is working towards being a barrister and he gets on with using a 12 inch iPad pro as his primary machine.
I'm replying late, but we use iMacs at work. The Mini could be replaced by an iMac at home, but I also need a Pro desktop for video editing.
