Building a better two-way pager

A number of people where I work have two-way pagers. Frequently they are walking with their heads down as they use both hands to type on their pager’s thumb keyboard. Does this strike anyone else as a bad interface?

Why don’t they make a two-way pager with a chord keyboard so you can use it one-handed and you could get bigger keys, also add a wireless (can you do voice over bluetooth?) earpiece (it doesn’t have to be wireless) that speaks what you are typing into your ear. This way you don’t have to look at the screen to know what you are typing. Heck it could even read your messages to you.

Where are all those voice command interfaces Negroponte fantasized about in Being Digital?
