I bought into the contour universe, which may have been a big mistake. The iPhone app was the deciding factor, but it's crap. At least my version is clearly "beta." Devices won't stay linked for more than a couple of minutes. And of course, as soon as you hit "record" the link goes away. I haven't actually tried it in a couple of years - it may have improved through updates. Customer service is nonexistent.
They also sent out an ad about a year ago for some horrendously expensive radio accessory that would broadcast the video to a remote base station. Way out of the realm of casual use, but it looked cool.
