One of the selling points of Apple's new Leopard is that it can work on older machines, and that Mac fans who are holding on to their legacy Power Macs can have a reason to rejoice once the Leopard OS gets released into the market. However, can Leopard really live up to its promise and run on an 8-year-old Power Mac G4 with AGP Graphics? Engadget tried to install the newest iteration of the OS X, and here's the verdict.

To cut the long story short, Leopard DOES work on an 8-year-old Power Mac, using only 5.9GB of space upon installation (that's without all the extraneous stuff such as drivers, etc). The question now is, what are the Leopard applications that work on an old machine, and what doesn't?

The new File Stacks and fans user interface worked, as well as Coverflow, Youtube, Quick Look, and Spaces and Expose. However, the machine choked on equally-important stuff such as DVD Player and Front Row.

All in all, it was a decent performance on a fairly old machine, and gives people reason not to throw out their legacy machines... at least, not yet.
