Forest nails it in the Forum — the iPhone and like devices have made it easier than ever to go anywhere and do anything with only a light bag or pack on the shoulder:
The iPhone has replaced so many things in my bag. I no longer take a camera, clock, computer, books,magazines, newspaper, movies, address book, datebook,or any of the assorted cords and ephemera associated with the electronics. I bet it has saved at least 6 pounds and maybe as much as 12 lbs.It is the most amazing tool I have ever used. Talk about muti function …. the holy grail of light travel.

This under-$10 sticker makes your iPhone into a lookalike of a $4000 Leica camera.
