Windows: Wanna give Office 2010's online document syncing, Windows 7 taskbar integration, and killer quick steps a go? Microsoft has thrown open the doors on a free beta of Office 2010 Professional—for those who can wait out the download.
As with the Windows 7 beta and most Microsoft offerings, this one requires grabbing a licence key, registering or signing in with a Windows Live/Passport account, and fighting it out with the many others trying to grab the download from the servers. The download is 684 MB, and Microsoft is suggesting users uninstall previous versions of Office before downloading—as well as asking that you "don't test Office Professional Plus 2010 Beta on your primary home or business PC".
Okay, sure thing, Redmond. Let us know if you've grabbed the beta, or found any helpful mirror links, in the comments. Office 2010 Professional beta is a free download for Windows XP SP3 and later systems.
