Mountain Lion now features connected standby via a feature Apple calls Power Nap. Even while sleeping your Mac will now fetch new emails, tweets, etc.. as well as download updates while it's plugged in. Power Nap is only supported on the 2nd generation MacBook Air or the new MacBook Pro with Retina Display.

So its not a stand-by by misiu_mp on Monday, June 11, 2012
It's gonna have to have the cpu, memory, disks, buses, NICs powered on to do this, so they shouldn't call it a standby or sleep.

The Connected Standby Microsoft proposes in Windows 8 is really really low power. Something even lower than current "sleep modes".
Likely the Mountain Lion version is similar. Though it won't be until Haswell we get that super low power Connected Standby. Right now with Sandy Bridge and Ivy Bridge its just idle mode + updates.

@DavidMelgar I've got a few ;) what have you been writing to it?
@rolphus @charlesarthur yeah it's clear that a lot of this is software related, scrolling under boot camp is fine
@rolphus @charlesarthur mountain lion shifts some of the burden back over to the GPU but it's still not perfect
@rolphus @charlesarthur depends on the workload, for a lot of the slow scrolling stuff it actually seems to be CPU believe it or not
@rolphus @charlesarthur it shouldn't, but it's an easy example of how not all drawing processes occur on the GPU.
@rolphus @charlesarthur …but many tasks are still done on the CPU (e.g. JPEG decoding, still CPU bound). We need faster CPUs & GPUs
@rolphus @charlesarthur it's actually both CPU and GPU. The lack of fixed function scaling in the 1680 and 1920 scaled modes hurts (GPU)...
@jjziv send me an email :)
@oddeiriknes I noticed it with the original Transformer as well, asked NVIDIA at the time but actually never got a response, will ask again
@oddeiriknes I've seen slowdowns when doing a lot of IO on a number of NV based tablets, I'm not sure if this is an SoC or bigger issue tho
