check out the Olympus Stylus "tough" series cameras. They are waterproof to either 10 or 33 feet (meaning rain is not even a concern), they use XD memory for super easy transfer to a computer (connect the camera to a USB port, or remove the XD card and stick it into the internal card reader on your computer if it has one), you can carry multiple XD cards for pretty much unlimited capacity, and the battery can also be swapped out for as much run time as you care to carry batteries for.
They are also rugged, so you can drop them and they still work.
They have a standard tripod connection on them, so they will work with any camera handlebar mount.
