jrepin writes with a snippet from the release announcement of Plasma Active Two: "Mobile devices that adapt to who you are, reflecting what you are doing when you are doing it. This concept is at the heart of the Plasma Active user experience. Plasma Active One was released in October 2011, providing early adopters the first opportunity to experience Activities on a tablet. Since then, the design and development team behind this open source touch interface has been hard at work on an update. ... information about real-world usage enabled the team to improve the end-user experience significantly over the past two months."
