I haven't pre-ordered, but was planning to buy one once they actually started shipping. I don't care at all about any advanced features -- just basic reporting and whether it will be able to wake me up at an opportune moment each morning.

It isn't entirely clear to me at this point whether I'll be able to do that without paying a monthly fee. It sounds likely that this may be possible, but I'd prefer to be sure before I buy.

Hopefully their website will clarify what is free and what is not before they begin shipping devices.
