>>The wristband tracks the movement of your wrist through the >>night, which it can use to analyze your sleep patterns. How is wrist movement co-related to sleep patterns ? Is there any scientific study / data out there that explain the co-relation ? Co-relation of pulse rhythm is more obvious - cant say the same about wrist movement. Anyone care to explain ?
Is there any reason to suspect its timed-wake-alarm could be better than just sleeping until you wake naturally? Also, I presume the analytics can be used without the alarm?
I confirmed with them that worldwide includes China too (so many companies do not ship there that I've become wary) so will be getting one :-)
Pre-ordered. Can't wait to try it. The techcrunch post has an error, by the way. It says you get $5 off when you pre-order.
Does it support polyphasic sleep? And is there an Android version?

The science has been done. The tests are clear. Polyphasic sleepers suffer performance losses in mental tasks compared to normal sleepers. In particular, it significantly impairs long-term memory coding.
Charlatans like Steve Pavlina always refused to do even basic scientific testing. His results simply can't be trusted, especially since he has a massive vested interest in it being effective.
If there is some reason you need to sleep less than 3 hours per day, then polyphasic is the best way to do that. However you will always have reduced performance compared to those who get a full 7 hour sleep.
If you want a sleep schedule optimized for creative/intellectual performance, free-running sleep is the best available. Piotr Wozniak has plenty of science of his website showing that this is the case.
Sounds awesome, but I don't use a cell phone. =( How hard would it be to get it to work with a laptop?

When I looked at the actual pre-order page, it doesn't seem like that is so. You pay $5, then you pay $45 later. Or you pay $50 when it comes out. What incentive is there, especially with an unreviewed product such as this? Will they tack on a subscription fee to use the device like the fit bit?
