Lovely snapshot in time view of the small computers that drive a ton of product innovation.
One major gap I'd really like to see covered better is power consumption. We've started seeing unboxing and reviews for the Arduino Uno Q for example, but no one seems to be breaking out a simple USB power meter to get some idea how much power it takes, headless or sitting at desktop.
Pretty nice that so many chips have pretty good Linux support.
I have some (somewhat older) OrangePis here that came with a board covering heatsink with an integrated fan because it turns out they really need it. The things get hot to the touch when working hard. I don't have any power measurement hooked up to them, but they have to be drawing a fair bit of juice to warm up that much.
