I have the Dasung display, so if its the same hardware then popping a different frame round it is not a big step forward.
To use it requires pissing about with display settings to turn on high contrast mode etc. The resolution is not quite good enough to make out buttons like close/minimise, but is *just* about good enough to work with code, but there are some problems. Typing code in a modern IDE has a lot of contextual information like underlines/colours that you miss, so basically back to notepad; a fair trade for being outside, perhaps. The main issue is OS support for greyscale is not good, everybody has a colour monitor and even in high contrast mode, using ubuntu is hard at times as menus are contextual and fonts are thin.
Plus the biggest issue, which these guys might actually solve, is I'm plugging an external monitor into a laptop, so the awkwardness of moving outside requires a table and power cords and faffing about. Good luck, cant wait for this to be easier! sun + code, yes please
