I echo everything RookieRoadie said!-- The comparison between road and MTB is N & D!! But no matter what you ride, it is nice to have a bike computer. It allows to push yourself when your ave is dropping over longer distances( i.e.: being more cognoscente of your wkout) and it's great for logging your miles & trip distances to and from places. You sound like you have the desire for one, so it'll just be a matter of time until you own one!

) acceleration, in particular, was much greater and I discovered that riding up hills at more than a snail's pace was indeed possible! You might find less of a difference between a road bike and your hybrid, but I'd expect it to be faster all the way around nonetheless.
