Microsoft has officially unveiled its Office 2010 software suite, and the upgrade boasts plenty of changes.

Microsoft is expanding its horizons with its newly revealed Microsoft Office 2010 software suite.

The updated Office will be available in two separate formats: a traditional PC-based edition and a completely web-based version. Both products are expected to be released in the first half of 2010.

Here are answers to some common questions about the new Office 2010 and what you can expect from a consumer perspective.

Will the PC-based Office 2010 and the web-based Office 2010 be the same?

No. The web-based version of Office 2010, called Office web apps, will include only Word, PowerPoint, Excel, and OneNote. The functionality in the programs will also be limited.

What'll you be able to do with the Office 2010 web apps?

Microsoft's Office 2010 web apps will give you full browser-based viewing and "lightweight" editing of any Word, PowerPoint, Excel, and OneNote files. The apps will allow for multiple people to edit the same files concurrently (a la Google Docs).

Will I be able to save files online with the Office web apps?

You'll have the option of saving files online, although you will have to sign up for a free Windows Live Skydrive account to take advantage of the cloud-based storage.
