RIM just pulled the virtual sheet back on OS 7. The user experience is familiar but RIM promises a system that’s both faster and better suited for managing a personal and professional life with a new feature called Balance. OS 7 packs voice activated searches and a retooled browser to better handle JIT JavaScript and HTML5 video. It seem RIM is most proud of Balance, which “presents a unified view of work and personal content…while keeping the content separate and secure.” Sounds a bit Nokia to me. Expect OS 7 first on the just-announce BlackBerry Bold Touch.
