I have a late 2010 iMac, and sometimes it spontaneously wakes up, usually within a minute or two of being put to sleep. Other times it spontaneously wakes up during the night. I can tell because if it's waking up from a true sleep, the wifi connection takes a few seconds to start up, but when it's just a blackened screen the wifi is instantly available.
