Question to all you GoPro users. If I spring for a GoPro, should I also get the LCD BacPac? I currently use a Kodak Playsport as my boat cam,but want something smaller & lighter for a helmet cam. I like that my Playsport has the built-in LCD view screen so I can check footage in camp, but the built-in screen makes this camera kind of heavy for a helmet cam. I wouldn't attach the LCD BacPac while filming, just in camp to check footage. If I have my iPod Touch along, could I just plug the GoPro into that to watch the footage????
