Well, I really hope this is just a stop-gap machine, or a sign that Apple feels confident they are selling enough computers that they can add new models to their line-up. I will absolutely never buy a "pro" computer that requires me to throw away the screen every time I get a new one and basically can't be upgraded.
I'm very much hoping next year we see a Mac Pro tower and a miniMac replacement line, perhaps just called the Mac, but more and more it looks like the miniMac is dead. This is really too bad since they made great little servers and media boxes. Apple I'm sure doesn't want to cannibalize their Apple TV sales in the latter category, but as long as Apple is making macOS Server, they need to have some kind of box for it, don't they? Please?
