Oh boy I’d like to play with something new and exciting like this and was sad to hear it’s just a design mock-up/idea. The OS space seems to have been quite stale for a decade or two, is there anything super exciting and different out there from a UX perspective? Remember installing Linux in the late 90s or rooting Windows phones and installing whatever latest Android OS was available in the early days of iOS and Android, and that was always quite thrilling.
