Inside OS X Mavericks
rjmarvin writes "Apple's era of naming OSs after big cats is over. The Mavericks wave is rolling in, and the first four developer previews have given an inside look at the cutting-edge OS. Users and developers have almost entirely positive things to say about Mavericks, from faster speed and improved stability to new features like iBooks and iCloud keychains. While some installation concerns and errors have arisen, developer preview have improved version by version, and Mavericks is looking good."
I smell horse shit. Panther was released in 2003 and ran only on PowerPC Macs. You're not going to be able to run Mountain Lion on any machine capable of running Panther.
