I'd be glad to try one (either blue or piss colored). If it really comes at 600€. Though it would already be 100€ too much unless it gets liberated to run linux at some point.
My fear is that it's going to be made useless in no time with software updates, or that it has some important limitation (like i can't use XCode command line tools)... But i wanted to replace my old mid 2012 for a couple of years and i decided the next laptop would be either ARM or RiscV (browsing, writing text, scripting, light programming)
