Palm on a Bicycle

all that's missing is a little meter that keeps track of how much time you're wasting by building this system.

So, you're riding along, and you're like, shoot, where am I going agian? So you whip out that handy stylus for that PDA, and you start writing. Pretty soon, you realize that you've let go of your handle bars, and run into one of those light posts that keep intruding where you bike.
is to get the magellan GPS unit. You get speed, plus you can create a log of your actual route. Absolute altitude is terrible on all GPS units, but you may be able to a pretty good slope reading. THe unit sends normal NMEA strings over a serial connection, so it's relatively trivial to write software for.
Magellan receivers lock on fast, and the handpring/magellan handspring module makes a nice, clean combination (relatively compact as a system, no external cables).
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.

It's not much of a hack if someone's done it before you and gave you instructions on how to do it yourself.
I don't know if it's my non-typical slashdot lifestyle, but I use my bike as my primary means of transportation. I live in Brooklyn, but affairs call me into the city nearly every day, so I end up biking about 6 to 12 miles 5 days a week. This would be a great secondary (albeit fringe) application for a handheld.
As for the breakage issue, I've been riding in Manhattan traffic for over 2 years now, and I've only had one accident so far. I've broken a lot more things by just dropping my backpack than I have wrecking my bike.
Finally, I think this could be the tool for messengers. I've done a bit of it and my roomate paid rent for a while pulling tags. The difference between a successful and unsuccessful bike messenger is not speed, its knowing where you're going and knowing how to get around the inside of buildings you make deliveries to. This would make a great on-board asset for professional messengers as it would allow them to share routes, both on the street and in buildings.
Think ahead a few years and a wireless connection would let dispatch download the next pickup or drop directly to the messenger's onboard computer. It would make them work a lot more like UPS or fedex.

Tape the PDA to your spokes for that cool noise effect.
"And like that
Yeah right, like I'm going to put a fragile $300 PalmPilot onmy mountain bike when I go terrorizing up and down trails and downtown urban rides.
There's really no use for this stuff, as there are bike computers that are more versatile than this which are cheaper and better integrated with the bike.
Take for example Shimano's excellent Flight Deck technology, which integrates with their higher-level drivetrain components (XT, XTR, Ultegra, and Dura-Ace).
Don't ride Shimano? No problem! CatEye makes excellent bike computers as well!
Another major consideration would be weight. Most PalmPilots weigh about 1/2 a pound (200g). That's a huge weight penalty, especially considering most people do everything they can to lighten their bikes.
Moral of story: good attempt, but bad idea. I'll stick with my Flight Deck.
