We all know the amazing pre-WWDC iOS 5 concept videos by Jan-Michael Cart. Today we got a new concept video demonstrating how iMessage could be incorporated into Lion in the future. It’s rather simple — the exact same proprietary protocol used in iMessage in iOS is put to work in Lion. iMessage syncs all conversations and messages across all your personal authorized Macs and devices (any device that uses your Apple ID).
Due to constraints put on by wireless carriers, I did not include the use of SMS text messages. Only messages sent through iMessage will appear on the Mac.
