First unveiled last October, Microsoft Office 365 is now officially available as a public beta. The service combines Office Web Apps with hosted versions of Exchange, SharePoint, and new collaboration product Lync, in an attempt to offer businesses a cloud-based alternative to some of its traditional desktop and server products.
For the security buffs in the house, this week also saw the release of Symantec's Norton Internet Security 2012 beta and Norton AntiVirus 2012 beta. The updates, while not ground-breaking, are definitely noteworthy, as support for Chrome has been added (a long-requested feature), and Insight 3.0, Download Insight 2.0, and Sonar 4.0 have all been improved.
Meanwhile, Mozilla has released a dev update of its own. More than a nightly build, but not quite a beta, the Firefox Aurora browser build walks somewhere in the middle of the road when it comes to stability and the latest innovative features.
