It's kinda too late for Austen (although the sleep telemetry might still be interesting), but the Trixie Tracker has FINALLY launched. If you're about to have a baby and you're (a) anal, (b) technophilic, (c) a fan of Edward Tufte, or (d) all of the above, get yourself over there and sign up. It's way better than writing everything on little index cards!
*Seriously, Benmac has totally outdone himself. The long wait was worth it.
