UX Evangelist published a post about the features Microsoft is considering for the future Windows 8 operating system. Here's a snip:
Are you a, "hibernate" kind of person? Maybe only in the winter (get it?), but if so, it appears that Windows 8 is going to contain a new Hibernate/Resume Integration API and a new TLZ file compression engine (I don't think TLZ is an acronym for the name of the engine, but rather an acronym related to TLA, or, "Temporal Logic of Actions" which you can read about here) that will replace Windows Vistas Xpress compression engine. One would assume the benefits of such a change will spell better performance via quicker hibernate/resume times due to the improved compression engine and however the new Integration API interfaces with it..
