Is Apple's Magic Mouse an Energy Vampire?

Apple's sexy, touchy feely Magic Mouse could be an energy-sucking vampire, according to a number of reports on the Apple Discussion Boards.

The present hypothesis is that the Magic Mouse is preventing the Bluetooth keyboard from entering sleep mode, resulting in weekly battery changes. One user purportedly contacted Apple Tech Support and was told the problem is a known Bluetooth driver issue and a fix is in the works.

Who here has one of these little energy vampires and what's your story? Anything? [TUAW]
