Well, the current USB-C to 10GBe is a big box (about two decks of playing cards) and costs about $150. I'm a bit unhappy about it. When a community college is starting to buy all 10GBe interfaces, its about time for Apple to move on.

I'm going to get two Mac minis to look at, and then wait to replace my current machine when 32 or 64 GB ARM machines are available.
