Today marks the launch of Apple’s new Leopard operating system, the tenth iteration of the software. Loyal Apple users took it on the chin when Leopard was delayed from its June launch until October to allow Apple to have the time to focus on launching its iPhone. For $129 you get over 300 new features for your desktop experience such as Time Machine (back up your computer’s contents automatically), Boot Camp (turn your Apple into a PC), a revamped menu bar that allows you to stack icons or folders, stronger encryption and firewall protection including something called Sandboxing which makes it harder for any hacker to remotely control your machine, enhanced wireless capture of images and many more doodads.

Reviews of the new Leopard are generally favorable. The Wall Street Journal software expert said “Leopard isn’t a must-have for current Mac owners, but it adds a lot of value,” while The New York Times sums up their review by saying “This Leopard has more than 300 new spots — and most of them are bright ones.” The bottom line seems to be that while Leopard isn’t a must-have for what it does offer it’s worth dropping your cash for.
