And yet the fact is every device which draws more than that invariably uses a propriatary connector. This suggests that there
are issues with trying to supply that kind of power over a standard USB cable. And as I said, Apple uses the same cable for charging and syncing. So if they used connector that could fit a standard microUSB cable there would ultimately be a lot of confusion. People would try using that cable with the charger, only to find that it doesn't work as it is missing the extra pins. They could fix a cable to the charger as the Nook does, but then you have to deal with an additional cable!

And the SB stands for Serial Bus... The fact is USB was designed to be a data connector, not a power connector. Charging high end electronics goes beyond what its designers ever intended.
