As a tandem instructor I used GoPros every day (had a glove that would stack 2 - one for video, one for pics). I used the GoPro 2 and specifically did not upgrade when new versions came out. The GoPro 2 was fine, it did the job, and I didn't have to deal with bugs. Also, I hate dealing with MicroSD.
If I were still jumping I'd use a Hero Session because the form factor is much smaller (rather than just slimmer).

What DZ do you jump at?
