Mac OS X 10.7 anybody? Or what about new MacBooks? Well, Engadget reports that Apple has sent out invitations for a special media event to be held next Wednesday, October 20th, at 10:00 AM Pacific Time (1PM EST). The event is to be held at the company’s campus in Cupertino, California and its tagline is “Back to the Mac”. The invitation also contains an image of what appears to be a lion peeking out from behind the Apple logo, suggesting that discussion of Mac OS X 10.7 will take place at the event. But who knows, PocketFullOfApps will keep you updated as time progresses.
