Yeah I have a replayxd 720 that recently broke and found the exact same thing...
Like hundreds of hours of riding footage that I did nothing with. Like I was ever going to learn how to edit video to an acceptable standard, and like my friends are actually interested in watching that shit. Reminds me of wedding photos... who cares?
Recharging and uploading actually ended up being more of a pain in the ass than it was worth. kind of glad when the replayxd died on me (I think the new ones are supposed to be much better)
Now pic related, a sena 10c, I could enjoy I think. It's bluetooth headset (necessity) with camera built in.
I'd probably only ever put a 10 second clip together for instagram though, if something particularly interesting happened on a ride
