abstuse, have you seen the size of some the items in question? i recently ran into a creditcard sized digital camera the other day and soon you can get a cellphone you can wear like a watch (even better with a wireless handfree system
).
allso, there is a reason for why you see more and more people with backpacks or similar, its a nice place to store stuff like a camera when not in use.
the stuff becomes smaller and smaller. motorola had a concept system shown of a year or 2 ago that had a pda/phone combo that you either had in your pocket or on your wrist. then you had a small digital camera with no real internal storage that you could clip to say the edge of a open jacket. all this and a set of "sunglasses" with internal stereo headphones/handfree and a small display. open top of that a pen that was able to work as a input device for the pda/phone and we are realy rolling.
point is that you dont have to have everything in your pocket. it dont even have to look like a phone or pda or camera...
