A comparison test today revealed that Mac OS X Snow Leopard is faster than Windows 7 in common tasks. Benchmarks run on a 2.53GHz MacBook Pro by CNET show that Apple's own operating system is about 38.5 percent faster in multitasking with media apps than Microsoft's platform and is also more responsive as a whole, taking less time to start up or shut down. iTunes audio encoding is also faster, though as an Apple program it's expected to run faster in its native operating system.
