For those that have the new GoPro 4 they have a new download out and it's good. It just updated my Silver & Black only took 5 mins a camera. Not like the old update which I wasted 2 nights on .

Full geek report below but the stand out features for me are:-

Time Lapse video:- This means it automatically stitches your 100's of pic together in a video format. That is Gold saves you hours.

Auto Rotation:- So no matter what way up mount the camera it records right way up , another big time saver in post production.

30 Shots in 6 secs:- It used to be in 1 sec that was useless you might as well video it.

If you are looking at getting one of the new 4's the Silver is the bomb. The Silver is just so easy to use with the back screen , heaps of battery life , doesn't run hot which means it will fog less in the sun and the vision is just so good. I use the Silver 90% of the time . I do have a LCD for the Black but it is so bulky compared to the Silver and it heats up and rips up the battery. The new cameras are the same size but the case is smaller but it also fits the old case , that's pretty cool Canon would never do that.
