The formfactor is self-imposed though, they could have made the device a few mm wider to accommodate a full HDMI port, but then it wouldn't be nice and square. Form over function maybe.
That’s what I do, the jetkvm has its “own” mini hdmi that follows it as I have moved it from different machines. Buying one cable wasn’t the end of the world (I was able to snag the jetkvm for $70 during its kickstarter and a $10 cord) and I use it constantly so it’s never collecting dust
