I digested all of Steve Jobs' keynote address from earlier today, in which he unveiled new operating systems for the Mac ("Lion") and iOS (version 5) as well as iCloud, Apple's new approach to syncing digital media, software, and data. Lion and iOS 5 are full of incremental improvements, some of them pretty dramatic jumps forward. It all looks pretty spiffy, of course, and instantly unleashes a new wave of tech lust! Apple has raised the bar once more and its competitors will be scrambling to stay in the game.
