Any new sensors/hardware not on a typical smartphone? Is the big advantage essentially a pervasive screen?

I ask because a common way to think of mobile app innovation is in terms of hardware advances: Mobile Data: Blackberry Email GPS: Maps, Local Services (Foursquare) iPhone 4 Camera Upgrade: Instagram The list goes on...

What's the key hardware advancement here?

What's the difference between a smart phone and a laptop? A smart phone can go with you everywhere to a greater extent than a laptop can. I think that glass would push that farther.
