At this week's Macworld, IBM has 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% space savings.
"To ease the mounting pressure on businesses to constrain costs, Notes 8.5 provides 'open' social computing benefits at substantial savings to businesses because less storage space is needed," said Kevin Cavanaugh, vice-president of messaging and collaboration at IBM.
IBM also announced new Lotus iNotes 8.5 software, which allows anyone with a Notes user licence 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.
