Nice find! Would be great if they had a version with a 10" touch display.
For sure. To be honest: the current screen size (5") makes touch on a normal Linux not very practical. Small buttons, small font.
But its processing power and its completeness makes the reTerminal very worthwhile. I am able to do arm-linux debugging on my desk now.
I work for years with industrial RasPi Displays from Maas.de They have other sizes also.
These are also very good indeed. But reTerminal is much cheaper, has a lot of (fast) emmc and is powered by USB-C. But again, the reTerminal 5" screen-size is a bit small.
