The thing I don't like about the fit bit is that it has no display; so there is nothing to prompt more movement on a lazy day.
I found something similar from polar...the polar 20 it's basically a watch version of the fit bit:

ter-Watch/dp/B001F0PVF8/ref=sr_1_1?ie=
UTF8&qid=1317936553&sr=8-1 But it has really mixed reviews so if I do order it I'm getting it from walmart.com so I don't have to worry about return/refunds.
