At work, I keep all my technology on my desk-- a Archos jukebox / portable HD, Palm m500, Motorola cell, and coffee mug.  All black-and-white "ancient" technology; I try to stay at least 4 or 5 releases behind the cutting edge.  Much better on the pocketbook.

If I'm not at work, the phone's in the pocket (where it has an annoying habit of changing volumes and going to speakerphone mode; damn external buttons), and everything else is in my free-for-showing-up-at-the-conference totebag.

BTW, anyone else bothered by the exceedingly short charge-time on cell phones these days?  I have to recharge about every other day.  My (archaic) Nokia held a charge for a good week (and was about twice the size...).
