What is a "switching" power supply? (ie. what makes it a "switching" type
ass opposed to what? a non-switching power supply?)

They appear to be used in all microcomputers (any exceptions?).  How come?

Why exactly is it that you're supposed to wait ~30 sec between switching
off and on again.

Just curious.

PS: please send me a mail copy of anything you post in response to this
as I may miss it as a news article.  Thanks.
