The new MacBook mini is almost certainly coming.
I actually think this is a very realistic possibility. The Mini was supposed to be the cheap switcher machine. But the PC market has become dominated by laptops since then. In some ways, a switcher device that's BYOKVM no longer makes sense; average PC users no longer have a separate monitor.
There are also rumors of a new "entry level" MacBook that may replace the MacBook Air altogether. Perhaps it's the same device. A new, cheap switcher machine; that's a laptop. And it's gimped relative to the Pro, but bulkier than the regular MacBook. Simultaneously it would be an excellent machine to target at the education market.
MacBook Mini or MacBook Edu anyone?
