Most significant Apple Apps were updated to run on Macs running Lion. Perhaps the most serious lapse was that Microsoft Office has some pretty serious problems that weren’t fixed prior to Lion being launched. Despite a long lead-in period through the Apple Developer program Microsoft’s Apple division allowed its most important Mac software title to go obsolete.

Apparently, most of the problems are related to major business related features such as the Communicator app crashing when launched. Outlook, the email client in Office can’t import files from Mac OS X 7 Mail client. Microsoft admits they don’t even have a plan yet to fix these problems.
