I have written a 10,000 word short story on my smartphone with a bluetooth keyboard. Sure, phones are not perfect but I don't see the point of owning a laptop after that experience. I think we are only at the beginning of seeing what is possible from a small, handheld device.

This. I am continually amazed at how few people use Audible. It is an amazing and rich source for books recorded in very high quality (read by voice talents, no stops during audio). I finish a book every 2-3 weeks just by listening on my way to and from class.

Grooveshark is another service I use my phone almost daily for. Play virtually any song on your phone.

Myfitnesspal is yet another. Record daily caloric intake and exercise easily (since you always have a phone around and since you don't know all the calories in the food you eat, but a search-enabled website does).

I also play backgammon while waiting for the bus.

I never take maps to unknown destinations any more. I still remember the times we printed maps before going to tourist destinations in nyc.

I check my email.

I check my calendar.

I talk on skype (via skype mobile). I do international calls without being charged international rates.

I check the weather (mostly the temperature) to know how heavy to wear.

I occasionally take photos when I need to record something (on a blackboard, for example) but don't want to write it down.

I got some free credit on audible, downloaded a book, discovered it's drm'd and none of my: laptop, mobile, tablet can play it. They just wasted my time - worse than useless.

I definitely take photos of whiteboards though and call via my sip provider.

Some of the best music that came out of the 50s was recorded on tape, then overdubbed, then overdubbed again. Creativity shouldn't be judged based on the medium.
