IBM’s software strategy is also embracing the Mac platform, with a new version of Lotus Notes and an integrated package of office productivity software based on OpenOffice and branded as Lotus Symphony being slated for release for the Mac later this year. Support for Notes email and calendaring on the iPhone and iPod Touch is also reported to be in IBM’s plans.
