I also bought it, and I am very enthusiastic about it. I will play a bit more and then post a review on the App Store site.
The thing i like most is that I can collect waypoint now and then while walking, I do not have to be tracking continuously, and thus drain the battery.
I intend to use it to track my daily walks on my walk to Santiago de Compostella next year!
One thing that surprises me is that it takes soo long to get a GPS reading, when the built-in Maps snaps the location in a few seconds. Is the GPSKit more picky with accuracy maybe?
So far, I also not been able to receive a mail with the waypoints, although it looks like it is being sent OK. Strange...
And what is Quick View??
