I'll admit, for a few hours, especially when TextEdit and Preview were crashing upon launch and I was having trouble adjusting to the new "unnatural" direction of mousing, I thought I had made a terrible mistake upgrading to Mac OS X Lion on launch day. How was I going to get any work done? With 250 new features, Lion offers a solid upgrade, especially when you consider the price is just $29.99. Of the 250 new features, though, there's a handful that have the potential to impact the everyday use of your Mac, as well as propel you into a new touch-focused Apple future.
