Ive just got the hero 3 white edition mate and its spot on. I had the same decision to make, the hero 3 white or hero 2 as there the same price now. From the research i did i found three hero3 versions the white, silver and black. the white is to replace the hero 1 same spec same 1080p record same 5mp camera juat better lens for criper pics. hero 3 silver to replace hero 2 again all same specs just better lens. then the muts nuts hero 3 black. i recon only for serious people wanting to make tv spec videos. the advantage of the 3 tho are they are 25% smaller, better mic and all have built in wifi to use the go pro app. Personally i went for the hero 3 because of the wifi and the fact you can see the view from the camera so no need for lcd back or wifi and i reckon go pro are going to phase out the 2 with the bigger body and so spares and cases might be harder to get, but thats just my opinion also the 3 has a better case for underwater shots
