Microsoft's Macintosh Business Unit has revealed details about its forthcoming Office for Mac 2011 suite, which the company says will be released in late October of this year. Office 2011 will be offered in two similarly named editions: "Home and Student 2011" and "Home and Business 2011." The Home and Student edition costs $119, and includes Word, PowerPoint, Excel, and Messenger. (For an extra $50, Messenger isn't installed. Just kidding.) If you need Outlook - which replaces Entourage - that's available in the Home and Business bundle, which will cost $199. Multi-installation licenses are available, too. Oh, and while Microsoft says there are only two editions, the company also announced a third version: "The Academic Edition" includes all the available Office apps - Word, PowerPoint, Excel, Messenger, and Outlook - but costs just $99. It's limited to higher education students, staff, and faculty, and anyone else who can disguise themselves as such.
