I've had the vivoactive3 for 2 years and none of the improvements in the vivoactive 4 are things I want. I would be very interested, however, if the memory for music could also be used for street maps. Every so often I need a quick map, and pulling out my cell phone, find shade to see the screen well, and running google maps is a hassle. I also want the watch to start gps with information from my cell so it can a fix much faster..
