My HP1 gets moved from my truck to the house twice a day so I think it would be real cool and conveniant if the followup to the HP1 had a docking type of connection (like the iPhone) so upon clipping the device into the cradle, all the connections are made at the same time. Four cables (GPS, power, antenna, and line out) get conn/disconnected every day... even better if the GPS module was built in eh!
Just my musings.
