It makes the camera a little bulkier, i wouldnt use it as a helmetcam if the lcd was attached it would be way too heavy. But it makes it just like any other camera in that you can see what your shooting easily. The playback feature is great, just one or two clicks and you can see what you just shot. They added a new button on the doors, to control the lcd screen. It makes it so you can turn the lcd on or off with one touch. On the lcd screen you can see your battery life, whether you in r3, r4..etc and whether your filming or taking a picture. Makes the GoPro a legitimate camera. Definitely looking forward to shooting with it in the park!
