If you've used the original Hero, this updated version will be a real treat. The menu is so much easier to navigate - no more obtuse codes to decipher. You can use the camera without ever looking at the user manual. Other improvements include LED's on top and bottom (as well as the front,) a more informative display, higher resolution for still images - this of course includes time lapse, and a 10 photo burst mode (the camera takes a few moments to store these out.)If you're new to the Hero line, this beats the pants of any competitor. The vast array of mounting options, both from GoPro and third party vendors make mounting this puppy anywhere a breeze. The fact that it uses SD cards (class 4 or above) keeps the cost down. and the tons of options make this a no-brainer. There's a Streaming video back being released shortly - yes - streaming video! You can add extra power using the USP port and any generic power supply (Aluratek, Belkin, or Tekkeon) for those really long shoots. The affordable replacement housing and parts are another big plus. I've seen this thing survive being tossed from a go-cart doing 50mph (It needed a new housing, but the camera was undamaged) and being knocked off a ski-helmet and tumbling down a rocky mountain face.
