Apple Enables 'Power Nap' for Retina MacBook Pro With SMC Update
Apple has issued a system management controller (SMC) update for the MacBook Pro with Retina display, enabling Power Nap support in OS X Mountain Lion.
This update fixes several sleep/wake issues to improve the stability of MacBook Pro with Retina display (Mid 2012) computers and is recommended for all users running OS X v10.7.4. It also enables Power Nap support for users running OS X v10.8 or later.
The update is available via Apple's software download webpage, Software Update for those under OS X Lion and via the Mac App store for those with OS X Mountain Lion installed.

because you get cool new features with them?
I'm filled with regret every time I gaze into the beautiful display of my rMBP. Luckily I can keep the lid closed while it does awesome **** for me now.
hahaha same here, and my cat :D
Umm... This is not a fix. This is a firmware update that enables Power Nap. It doesn't matter when you upgrade to Mountain Lion, you'll still have to update your firmware to use Power Nap.
Maybe try disabling all that extra crap you have running first.
