Someone Call Bill Gates for Me

Over at Dean's World there is an interesting post by Scott Kerwin entitled "Laziness: The Unappreciated Virtue." It concerns, in part, hand held electronic devices and their ability to make our lives easier (or not). In the comments section, I left the following:

I want a single portable device that can be my "everything" - a phone, two-way radio, computer, camera, TV, UMD player, universal remote, credit card, car key, garage door opener, emergency alarm and self-defense taser-like weapon. I'm thinking something on the lines of the "Dick Tracy Walkie Talkie Watch" only it would, by necessity be somewhat larger - maybe 4"X6", extremely FLAT and flexible, that could be strapped comfortably to my left forearm, but easily removed so that I could work it with both hands in front of me if I desire. When's THAT coming out? I'd gladly pay $400 a month and junk a bunch of other expenses.

Has anyone heard of anything along these lines being developed? If not, just remember you heard it here first because I want my intellectual royalties cut. It will eventually come and it won't be too soon for me.
