Is mulitasking good for us?

The digital age brings us technologies that are supposed to help us do more. Are the phones, pads, net, etc. helpful to our development of knowledge. I think you'd be surprised if you watch this video from PBS. I posted this as a result of a conversation I had with one of my students who insisted that technology has assisted multitasking thus doing more at one time and of course getting smarter from it...think again. Take the plunge and respond if you'd like.
