The invites just came out from Apple inviting the media to an event focused on the Mac. The Mac business represents nearly 30% of Apple's revenue so updates to the Mac business are important in our eyes. This event will happen just days after Apple's earnings call on Oct 18th which means Apple will get plenty of media attention throughout the course of next week.
It appears the event will be focused mostly on the next major OSX release which is obviously going to be called "Lion." Other potential updates could be an update to the MacBook Air and iLife '11. Suffice it to say we are very excited to see what new features Lion will bring for the Mac consumer. SlashGear will be there live so check back for full coverage of the news and On Time Analysis next Wed at 10 A.M PST.
