I bought a GoPro Hero3+ Black and a bunch of mounts and accessories a couple of months ago and I've been perfectly happy with it UNTIL I played with Sony's new entry into the POV camera market, the HDR-AS100VR/W, it looks spectacular! I wish I had been paying attention, I would have very likely bought the AS100V instead of the GoPro. It has stereo audio, Steady Shot, GPS and a very cool Live View remote (as well as a smartphone app), and the body is "splashproof" outside of the included waterproof case. It also has a "Pro" mode which records XAVC-S at 50mbps, Vegas handle it just fine. It's $400, the same price as the GoPro Hero3+ Black. (It's also available for less money without the Live Remote.)
Here is a pretty in-depth 35-minute review of it from Techmoan on his YouTube site:

He also has some 50mbps 1080-60p Promode clips you can download via DropBox from his blog.
(Truth be told, while I justified the purchase of the GoPro for "professional purposes", I basically bought it to mount to various places on my sports car and record me "hooning" around on Northern New Mexico's mountain roads and all their gorgeous scenery. High frame rate at a high bitrate is highly desirable.)
