			The Tablet and the Color both have custom MiniUSB ports (and cables and chargers) that have extra pins to allow for faster charging.  Use of other cables and chargers (including a computer) will either 'trickle' charge or potentially discharge the battery depending upon what's happening.   YMMV, [insert other disclaimers here],.... 
 
It's easier for us to say just use the charger/cable in the box, than it is to provide a properly nuanced view in the user documentation, since no matter how carefully you write something like that, you will never get it quite right (and customer complaints/lawsuits etc follow).
