BodyMedia Fit armband?

I've been looking also, so I want to pay attention to this one.
BodyMedia Fit doesn't have a heart rate monitor to it, but apparently it can link to one, or there is the option to do so.

I wear mine all day every day. It has been a real eye opener for me to learn how active or inactive I have actually been. Apparently it is 90% accurate and clinically endorsed. I have been happy with it so far except for one thing. It counts activity while I am driving. I emailed the company and the only solution is to take it off while on long drives. I don't think thats too much of an issue. Probably remembering to put it back on would be more of a hassle though. It also measures your sleep as well which has been informative. I have learned that I only average 6.5 hours of sleep per night where I had believed that I got between 7 and 8 hours. I think it is way better than a pedometer as it counts your entire days activity rather than just steps.

Thanks for the feedback Phee! Mine should arrive tomorrow night...I can't wait!
