Wow, it's so interesting how many features are on these phones that some consider nothing out of the ordinary and others (even experienced Android users) are completely unaware are even there! I've known about Voice Commands for ages (well, ages in smart phone terms, i.e. the last several months). It works incredibly well. Still, there are always things I discover from others that I didn't know as well. That's the beauty of this open forum. It is a true community of people helping people for the better of all.
Perhaps the US Government (among others) could learn a lesson or two here!
