AFAIK that's correct about Apple. A lot of manufacturers really blow it, drawing too much power from USB on the hope that the computer manufacturer isn't hitting the spec any better. Then there are the laptops that provide little or no power to their USB ports. The problem with USB is that it isn't, Universal. Or as I like to put it, the wonderful thing about Standards is that everyone does them differently.
