Recently the TUAW guys have discovered a new feature in the Lion application Preview : the application will be able to open Microsoft Office documents .
So far we have been able to do so using QuickLook in Snow Leopard, but we couldn’t open Word, Excel or PowerPoint files unless we had an office suite installed on the computer (iWork, Microsoft Office, OpenOfficeLibreOffice…). In Mac OS X Lion we won’t even need iWork to be able to look at those documents, and we won’t be forced to do so with QuickLook. Preview will offer us a slightly more complete way to view those documents . What you get is basically better compatibility with Office documents when you first start using a new Mac.
Remember, though, that viewing and opening documents does not mean that we can edit them . For that we’ll still have to install any of the applications we’ve mentioned, or use some of the web tools capable of doing so, such as Google Docs.
Mac OS X Lion is expected to be completed and featured at the next WWDC 2011, although it could be released to the public weeks later.
