In a phrase: compact flexibility. My big, heavy 2011 27" iMac died and I am trying to decide how to replace it. While waiting I am using an old MacBook running a 27" external monitor front and centre on my desk. I like that setup much better than having the iMac in front of me, mainly because it takes seconds to switch over to my little work Windows laptop. If I get an iMac, I won't be able to do that (use the imac's screen as an external for the work laptop). So a Mini would be ideal. Easier to plug in external drives too. My wish: quad processor, 1 TB SSD, four USB C ports. Flexibility in a compact package. Sigh.
