Many people are choosing between the Zen, the ipod, and the Karma, and if this was your field, then the Karma is by far the thickest and the least pocketable.

I dunno... My car keys are bigger than the Karma.

I think the Karma is more pocketable than the iPod because of its other dimensions. I agree that it is thicker than the ipod, but the other dimensions of the ipod make it less pocketable in my opinion.
