А что, чем не ЛонгХорн? "BRiX is not a conventional operating system and some of its new features include:
Small, fast and responsive -- There is no reason why operating systems should be bloated, slow and unresponsive. Data-centric -- All data is stored in a flat filesystem and accessed using search queries on the attached metadata. The traditional hierarchical filesystem requires the user to remember where files are stored and what they were named. An easy-to-use graphical interface plugs the data into special interface objects that provide multiple means of viewing and modifying the data. The traditional approach launches applications to display data and requires the user to manually launch additional applications if the default is not what the user wants. Persistence -- All changes to data are automatically saved and can be undone even after the current session has been closed. "
