Like it is reasonable to expect Mac users to spend $150 for a windows license, (and then pay $79 for Parallels or Vmware, if they don't want to completely reboot into Windows everytime they want to upload data*) just to be able to upload data from a pedometer. I decided to spend less than half that and buy a FitBit, which was already Mac compatible. *I know it may be hard for Windows users to believe, but I don't regularly reboot my Mac. I just put it to sleep when I am not using it. I only reboot when there is occasionally an OS update that requries it.
