> might have very serious consequences on how we work as biological beings.

its a little late for that.

but personally I liked getting a smart phone because it meant I didn't need to be around the computer and could still handle emergencies or react to opportunity. or just keep connected with people in different continents while walking through my city.

I think these devices are the gateway to getting away from the Television and a Typewriter interface. Its a way to get back to being present but still getting the advantages of being connected.
