Have any owners of the new MPB notice any difference in sleep performance? Specifically do you have "instant" on from sleep and low battery drain when sleeping?

The reason that I ask is I remember these as being big changes from OS9 and below. Took several seconds to wake from sleep. But the battery drain was vastly lower than the introduction to OSX. I'm assuming that both hardware and software are important here so with a radically different processor, I'm curious if there is a noticeable difference.

Even today, I notice most Windows users boot up every time they use their laptop at places like coffee shops and airports. Makes me wonder about Intel's power management features while sleeping.

Windows is not a product of Intel and has nothing to do with the chips inside the MacBook Pro. Windows users boot their PCs up every time out of habit. They likely tried sleep a few times when they got the machine, and discovered it rarely works right. So they turn the sleep option off and move on.

The MacBooks wake from sleep just like the Powerbooks did. They go to sleep about the same speed too. They do use the Safe Sleep feature introduced on the last generation Powerbooks, so even if the battery does drain, the system will boot right back to where it was. Think of it as hibernation that Windows offers, but automatically done and not something separate then sleep.

Nice to know there don't seem to be differences in sleep. Does that go for battery drain while in sleep mode as well?

And if I understand what you are saying is that sleep is completely an OS function, does not need chip support?
