an external internal organ

Nothing fancy here, more of a tweet than a post. It just struck me, riding home--and remembering back to the days of carrying my computer in a saddlebag over the back wheel of the bike--that in the backpack the computer feels something like an internal organ. Not hanging out over the pavement and liable to being knocked or bouncing off, but weighing on my back, 5 inches from my lungs, and liable to go down only if its rider goes rolling on the street...

The computer, like a vital organ even in transit. Kind of odd.
