Microsoft Office for Mac 2011
Until recently, I didn't realize that the latest version of MacOS X, (Lion), won't support applications that utilize the OS software, "Rosetta." If you are like me, you probably have a large number of applications that require Rosetta. Like my older version of Microsoft Office.
So, I am patiently collecting applications that will run with Lion. Like this new version of Microsoft Office.
Until then, I won't be upgrading the computer I use to the new MacOS X version, Lion....
