Friday the 13th. I mean Slimbook report no.13. 'Tis an ongoing review of my Slimbook Pro2 & Kubuntu 18.04 Bionic Beaver experience following a series of meaningful, real-life use cases, including ergonomics, performance, battery life, driver management, various regression in smartphone connectivity, DOSBox and system shortcut conflict, application hangs and crashes, and more. Have fun.
