If you want something that will basically reacord all that useless data and have money to spare the Suunto X10 (2010 Model) is an awesome wrist watch GPS, as long as you are not looking for a GPS that will be giving you turn for turn directions you can view all the data and at the enfd of the day you can actually download it and overlay it on google maps and see every hill you went up and how much, every turn you made you current speed at any point along the route etc. they run about $450 though. I wish I coudl afford one but I have other more pressing priorities. If you know you cloud types and and use the barometric bressure you can amaze the other riders you are with with you seemingly magical way of pitching a tent always just before it starts to rain even if you can't tell a storm is coming.
