I think it is a huge game changer. You'll see. Just wait 'till you have DialCentral (with free long distance and SMS) on your phone. Just wait till you have a contact record for a person with Skype, MSN, ICQ, Google, Yahoo, Facebook (etc, etc) IDs (and presence indicators!), e-mail, and home/office/mobile numbers, and you can choose to contact that person using any one of those methods from your mobile device. Send them a Skype IM? SMS? Call them? e-mail them? Sure. Just hit the button.

Are you in a WiFi area? Well, use one of the several supported VoIP protocols over wifi instead of 3G.

Shoot a DVD-quality video of your daughter at dance class, and send it immediately, from your device, to your spouse on a business trip overseas.

Sure, you'll argue that most of this can be done already, and this is just an incremental step, but you can say that about a lot of inventions that seemed minor at the time but later turned out to be real game changers.

Anyway, time will tell. I'm probably just a hopeless fanboy.
