There's a lot to love and like about Mac OS X Lion, but it's far more disorienting and confusing than I ever imagined. I've been using Macs since the early 1990s, and I faithfully upgrade to new versions of the operating system quickly. The original Mac OS X was a pretty big leap, but Lion, it sure seems now, offers more in the way of interaction transformation than I ever expected. My first conclusion: It's going to take me a lot longer to get familiar with all the new features and ways of interacting with Lion, apps, my content and workflow.
