The reason I ask what you will be using it for is to determine which set of features you need. If you're going to be using it for simpler activities, don't go all out for a Black edition with a 60fps, 1080p cam (all HERO3's are 1080p, anyways). The reason the Black Edition is so expensive is because of the crazy quality it has, and if you're using it for a more simple basis I wouldn't worry about the difference. The Silver or even White is perfectly fine for you. The main difference between these two is the white's camera has a 5 megapixels with 3fps burst while the silver is 11 megapixels with a 10 fps burst -- is that worth $100 to you?
Is GoPro still the best action camera?
The HERO4's come with only a few mounts and do not come with Wi-Fi accessories because it's built-in! If you're looking at getting a brand new GoPro and the best of the best, the HERO4 is what you need to look at. In our opinion, the Black Edition at $500 retail is a bit steep and is geared more towards movie makers and professional studios. What we found interesting was the fact that the Silver Edition has a built-in LCD but the Black does not. Is this important to you? Also, the 4K cinema at 30fps with the Black Edition is crazy; however, it eats up a lot of battery. The Silver Edition films in perfect 1080p which is the standard for most playback devices, so going with the Silver as opposed to the Black is more recommended in our opinion.
Can GoPro hero 7 take pictures?
You get many of the same shooting modes you'd find on a GoPro device, such as time-lapse photos and videos and slow motion footage at 1080p at 240 fps, and there's even a Drive mode so you can use it as a dash cam when plugged into your car, automatically turning on when you start your car and off when you stop it. It's not waterproof on its own, but a dive housing is included as well as several mounts, two batteries and a charger that simultaneously powers up both packs. It also has built-in Wi-Fi so you can connect to a smartphone and use an app to control the camera and transfer your shots for sharing.
