I think the point is that it should only use a tiny bit of power as it presumably keeps the processor at the lowest clock-speed, maybe forces the use of only one core, and since it requires an SSD there should be no significant heat, no need for fans etc., so power draw should be tiny.
The decision is whether you want to trade off a small amount of power drain for ensuring that syncing features continue. That said though I really don't see the usefulness if you're on the go, as you're unlikely to have access to Time Machine, and the last thing you want is your machine to be trying every nearby WiFi hotspot in an attempt to get online for e-mail etc.
Result is that this is most useful for a machine that's plugged in to charge at home, as you can save power without interrupting Time Machine backups, and when you re-open the machine it'll be up to date on e-mails etc.
Firmware update.I have an SSD, Retina Macbook Pro, Mountain Lion.
No PowerNap.
WHAT GIVES?
Firmware update.
But where do you go for that? I don't see that I have any updates that I need to install in the Mac App Store..
Weird thing I'm waiting for the firmware update for the MBA 2010 but I am not so sure Apple will deliver.
But doesn't it only work when you have have power plugged in?
You can choose if you want it to run while on battery power.
I wonder if this will eat the battery when my mac is asleep?
ah there we go
I don't see this on the macbook retina? I guess there needs to be a firmware update released for it?

I believe it's only active when the laptop is plugged in.
I can imagine it being a 2 tiered service though. While the laptop is plugged in it backs up and downloads updates. however if it's not, it just receives emails and notices. That's low level functions that iOS devices do while "off" and it barely touches their battery life.

ah there we go
I was mistaken. Here is the correct info. I edited my post above.
In your screenshots, why are the 2 options above the power nap option greyed out?

Because I have my system set to automatically lock system pref panes. If you click the lock at the bottom left then enter a password it will ungrey (<is that even a word?) and you can change the settings.
Maybe because it's locked and he has security set up to block access.
Can you guys update me on if there's more proof of the firmware upgrade on the late 2010 Air? I saw in an earlier post a guy had it, but still not completely positive?? Thanks!
