I've got an Apple Bluetooth keyboard (the shortboard) and it's fine. I like the keyboard on this little Pro I'm using (at 2013, it was before they lost their minds with the butterfly?). But I do use a mouse if I'm doing any drawing or whatever. But I like the trackpad too, all the gestures.
I'm not in a position to do anything this moment, and by the time I am (January/February) the 2020 rumor mill may wind up factoring in.
I may just use this little loaner longer than I plan on. It's certainly nimble (I imagine that's the SSD?). I love how most everything launches in a single Dock bounce...I've been accustomed to 15-30.
