Is there a way to tell how much time you have left on your battery other than seeing it at "half" or "full", etc? Is there an indicator anywhere in the touch that will show, for example, "8 hours, 3 minutes"?
Not with the current software.
I'd imagine there will be utilities like that when the SDK comes around...
FWIW, utilities like that on portable devices are generally not much better than the status icons...the power supplies aren't nearly as sophisticated as laptops, for instance.
