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.

You can fit a standard USB to non-standard chargers (like the NookColor charger), and it will simply tickle charge, or not charge at all, because it has no pins for the additional connectors. There is no problem, and you can make it even easier by making the charger cable non-removable. Likewise, you can use the NookColor USB cable as a standard USB cable, the additional pins remain unconnected. Really, there is no reason to use proprietary connectors for phones/tablets. And that goes for all companies, not just apple.
