Mac OS X 10.5.7 Optimized for Intel Atom Netbook/iTablet Class Processor?!

Yeah, this story is thin. iPod nano thin. But Wired (via MacRumors) is claiming that Apple recent Mac OS X 10.5.7 Leopard update gives netbooks running the software (aka Hackintoshs) a significant boost to battery life (up to 33%).

This has led to some speculation that Apple maybe -- just maybe -- built in better power management and other optimizations for lower end processors like the Intel Atom.

Of course, that type of speculation is but one tiny little step to yet more rumors of Apple preparing to launch a netbook-like laptop of their own (or perhaps a full own OS X iTablet).

Hope springs eternal... especially when spring is right before WWDC. TiPb's still leaning towards a larger-screened iPod touch as being more likely, but what do you think?
