Ok, yep, this is pretty solid.
It's also pretty hard on the battery
Off charger @ 6am... 7am-4:30pm GPS Logging every 30 minutes, with 2 20 min sessions on car charger running Tom Tom, light use otherwise - some surf/email/talk down to 68% - normally would be in the mid 70s with that usage.
Not killer battery drain, but not nothing. Still, pretty neat.
You have to have some kind of lock to use this thing, it needs a good 20-40 seconds to get a lock. Seems to like to run for 20+ seconds even after it gets a lock even on the lowest "quick" setting for fix quality.
Overall, pretty cool. I've got a mortscript that snaggs the fix and posts it back to my web site for my own nefarious use. Muwahahaha....
