To quote from the excellent movie "Spinal Tap," "it's a fine line between clever and stupid." I may have fallen off that fine line in writing TidBITS-114, because despite a few clues and hints, the fact that it was indeed our annual April Fools issue appears to have gone generally unnoticed. Almost everything in that issue was false - though often entirely possible and even intensely desirable - with the exception of the IBM marketing move (which was strange enough to be an April Fools joke), and the Dolch projection panel (which I used to make the last article more believable). Sorry folks, if I threw you for a loop.

Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
