IBM (NYSE~IBM) announced the availability of Lotus Notes 8.5 collaboration software with social computing features for all Mac OS X Leopard-powered computers. In addition, IBM’s free Lotus Symphony document, spreadsheet and presentation software will be available later this month for the Mac. Lotus Notes 8.5 provides significant storage savings over previous versions. Notes has an intelligent storage savings feature that ensures that only one copy of an attachment is kept on the mail server, resulting in an estimated 40 percent space savings. Lotus Notes 8.5 arranges all collaboration tools on one screen in fewer clicks. This screen shows links to team rooms, instant messaging, to do lists, calendar, Internet browsers and other tools. Social characteristics include new integration with Google, Yahoo, and hundreds of other public Internet calendars. IBM also announced new Lotus iNotes 8.5 software, which allows anyone with a Notes user license to access Notes through a Safari browser from anywhere. iNotes allows the user to integrate the Notes calendar with Google calendar and also supports most standard widgets. One example of a widget is the mapping of a street address in an e-mail note. IBM sells Lotus Notes and Domino in a variety of ways, including packaged with hardware for small and medium businesses; via a hosted service, where the software is stored on a server at IBM; and through Passport Advantage on http://www.ibm.com/lotus/notesanddomino.
