I'm sad about this as well. The Zeo has been the only QS thing that I've been able to get my girlfriend to use, and it has increased her understanding of her sleep patterns dramatically.

I now look back with a twinge of anger at all the times that someone told me that they track their stages of sleep too, but with their iphone app and "it was only a dollar."

And to be clear, you can only upgrade the firmware on the Zeo bedside unit, right?
