David Pogue nicely captures the inspiration Apple's new "Lion" operating system drew from the iPad and its OS. If you have an iPad (or iPhone or iPod Touch, all of which use the iOS system).
One point he didn't make: alternating between Mac and Windows will now be more confusing.
Mac and Windows essentially reverse the functions of the "control" and "alt" (Windows)/"command" (Mac) keys. Many keyboard shortcuts, such as saving, involve those keys. Saving a file is "command + s" on a Mac and "control + s" on a Windows PC. We are all creatures of habit, and if you switch back and forth between the two systems, you constantly mix up the keystrokes.
Lion now changes the way the you scroll especially on notebook touch pads, so that what used to be an upward scroll on both Mac and Windows now requires scrolling down on Lion. As all reviewers have noted, this messes with your mind when you first use the new Apple OS.
While you may eventually adjust your habits if you stick to an all-Apple world, going back and forth from Windows to Mac will leave you permanently confused.
