Fitbit or Bodybugg?

Hello everyone! I'm trying to decide between buying a fitbit or a Bodybugg. Does anyone have an opinion either way on which is better? I'm really interested in seeing how many calories I actually burn in a day which leads me to believe the Bodybugg is better...but it's so BIG! I just can't imagine wearing that thing 24/7! Any suggestions/personal experiences would be really appreciated!

Thanks!
Heather
