I cut and drilled a plastic clipboard and fastened it to clip-on aerobars with zip ties. I use two large clips on either side to prevent the pages of my surveyor's level book from flipping while I ride.
Here is a photo of something I've been playing with.
I usually measure with a 5" x 7" notebook in my right hand, which limits me to one hand for braking and shifting and effectively gripping the handlebars. I wanted something that would let me ride and brake with both hands and give my bike more than three gears.
This device consists of a plastic translucent clipboard with the clasp relocated from the top to the side to hold the notebook. On the other side I'd place a PDA if I could find a hard case that fits mine and would open the way I want it to. It's attached to the handlebars with a device called a swing grip which I bought at my local bicycle shop.
I wanted to be able to see through it so that I could see the front wheel and a Jones Counter if I needed to use an original with the display at the wheel. I needed to be able to detach it because I transport the bike on top of my car and the wind would wreck it if I couldn't.
I'm not sure why I haven't used it more than I have; I really don't think the PDA is all that important although it would be nice to have it calculate splits.

Mine is a lot less elegant, but it only took me a few minutes to design and mount. I use a 5x7 clear clip board that I zap straped it to my handle bar stem (through 4 drilled holes). I added an enhancement by using duct tape to attach a small tube which I use to store my pencil when I am riding. I have not had any trouble with the wind damaging the clip board or its mounts.

I recall from the 2000 OT marathon validation in Pittsburgh that Wayne Nicoll had a rat trap (a real wooden rat trap, that would doubtless break if not amputate a few fingers if they were whacked w/ it) mounted to his handlebar. The spring on the trap mechanism exerted penty of force to hold his notebook in place.
