Apple has released the next major update to its Mac operating system. Mac OS X Lion, which is currently available only through the Mac App Store, serves as a great indication of Apple's future direction, and not just because it integrates the most successful aspects of iOS. There are changes afoot in the world of personal computing; Lion may well be both a beginning and an end. Check out John Siracusa's incredible 19-page review on Ars Technica for a complete breakdown

As always with major system upgrades, due caution is advised -- backup your system, research app compatibility, and be prepared for problems. Many older emulators will likely no longer work, as Lion drops PowerPC support altogether. Richard Bannister notes that all current releases of his emulators and other programs are "believed to be compatible," with the sole exception of audio editor Cacophony. Many others, as you'll see, have put out updates to address Lion compatibility.
