I think that in order to have a second smartphone revolution we need to look beyond the mobile operating systems that we rely on today, none of which seem optimal for the emerging markets (including Tizen and MIUI) considering the expensive high end hardware that they target. A hypothetical initial focus on supporting productivity and business applications by a small team that could take this on could help narrow down the list of hardware to support as the need to compete for the latest CPU or the best video chip is reduced. Also, I was wondering if Rust could be to a new mobile operating system what Objective-C was to OS X and later iOS serving as a layer on top of C/C++.
