I purchased a MacBook M4 Max for my business as a consultant even though I had a Mac mini m2 pro which work fine and was only barely 2yrs old. I love the MacBook max with nano texture, easy to look at and read for long periods and less strain on eyes. I was going to get rid of the Mac mini, but I find for 90% of my tasks there is no really big difference in speed, unless I'm doing serious video editing or large coding. Do any of you find that you are still using your older Mac more often than your newer technology or should I just get rid of the Mac mini and stop holding on the older as no reason to?
