I like the most things they have done to kernel, particularly removal of Big Kernel Lock, or IO throttling. But I like some day to see a power manager as good as what OSX has.

OS X has piss poor power management in and of itself, it's the Apple drivers and tweaks that allow it to be efficient. You can do this in Linux too, but it takes more work and some understanding of how ACPI works.

OS X does not have to support as much software. And when you buy a windows laptop the laptop manufacturer installs it's "own" drivers to make it efficient.

So the Linux developers have a lot more work to do.

But if you are unhappy how much power your Linux-based system uses, I suggest running 'powertop'. It will help you with all of that.

Based on what evidence is it 'piss poor' or is this more 'speaking out of your ass' rather than using empirical data?

The efficiency in terms of power management has as much to do with the kernel as it has with the user land applications and how they're written. If an application is polling non-stop for a device to be inserted then it won't matter how efficient the kernel is given that an application in user space is constantly waking the CPU from its low power state.
