I have the F4 and love it, though I don't use it for any kind of summary purposes over a length of days -- I just want to see my calories burned and heart rate for any particular workout. I also don't work out in a gym, so I didn't need coding.
Every once in a while, it asks me if I'd like to go on a bike ride . . . and recently, it's been showing me what appears to be the flag from a golf hole. It's a funny little devil.
