I too was surprised. It might make me put a little more thought into my next upgrade. Although at the moment I am still leaning towards the more expensive Odroid-N2 as it has more processing power.
I have a RPi4 4-gig sitting on my desk that I want to use for AP. Since the libraries for apps like KSTARS haven't been updated for Raspbian [and other applications], could I still use it to make a full AP software host while I wait for MATE?
