Enterprises packed with smart people probably forget countless good ideas before they ever have a chance to become profitable innovations. That's especially true when all the voices on a collaborative team are clamoring to be heard, whether in a real or virtual meeting room. And that's where Evernote can help: in simple terms, the service helps ensure those ideas don't go to waste by capturing them as text or audio notes. A host of sorting and search functions help keep them organized. The premium version comes with, among other upgrades, enhanced collaboration features such as the ability to edit others' notes. ("Sponsored Accounts" provide a company-wide license.) Evernote's free iPad app (and its other mobile versions) creates true mobility, and the larger touch display makes things like clipping Web content for note purposes that much easier.
