I've heard from many of my MFP Pals that the Fitbit is a glorified pedometer, if your doing something other then walking, it really is not accurate. However, it does track sleep.
I own a BodyMedia and have had it for 2.5 years now... I personally LOVE it.. Here is why:
It has sensors on it that base your calorie counts off your Skin Tempeture, your blood flow as well as your movement giving you a 95% accurate reading in most activities. This is even more accurate then your heart rate monitor (I also own a FR60).
The interface is FILLED with good graphs and data, including Calories Burned, Calories Eaten (which can be synced with third party apps), Steps Take, Activity Minutes which gets sorted down to Light, Moderate and Vigorous, and Sleep. As well the interface gives you your personal best for each category, and if you turn on Fit Coach (which is optional).. it will congratulate you, push you and direct yo to meeting your goals! I love when my monitor tells me that I've done a great job, but I also love that at 2pm on any given day when I load my data it might say "Hey your below your target today, jump on the treadmill for 30 minutes at a speed of 2mph to reach your goal" and then give me other options to reach my goal as well!
I had a custom band made for mine, because my arm is bigger than the band that came with it, but they do have S, M, L bands... and I wear mine for most of the day (an hour to load data) and many times have to check to see if it's there because I don't feel it.
As for the Android/IPhone interface, I don't use it, because I don't have the link and I feel it's pretty much useless if you don't buy the LINK version (which is bluetooth).. as the app is no good unless you can stream live data.
Other then the app being no good for non LINK users, I have no gripes about mine.. there is a monthly $7 fee to use the website, but I feel that with the data I get, it's well worth the $7, plus you get a free 3 months when you activate a band (this applies weather you buy it new or used)..
I've learned a lot about my activity levels (like the fact I barely move at work) and its' done me a great deal since I got it! In-fact I just bought one off ebay for my SIL!
