> For the average user, Hands Free permits easy browsing while eating or multitasking,

How can you eat and utter voice commands at the same time?

I think the point is that your hands may get greasy or have food bits on them and you can still browse without getting your keyboard dirty.

Spraying out food particles and spit all over the keyboard and monitor is ok then! :)

As the saying goes, "It's not polite to talk with your mouth open."
