OK so I purchased a Polaroid XS100
http://polaroidaction.com/xs100.html in April 2013 for $200 to my door from Amazon.
Since then they released an upgrade with a Bluetooth connection to you phone for about $40 extra.
This camera is basically a generic camera made in China and badged for a number of retailers eg Ion, Polaroid and Action, possibly the innards of the Contour+ as well.
ProsCheap - especially when compared to the GoPro
Compact - especially when compared to most others
Excellent Video, close to, if not as good as the base GoPro
Slimline - idea for helmet mounting - no drag
Record time - approx 3 1/2 when new
Probably just me but Colour as well - White
Waterproof to 3 meters - Tested and it is - takes excellent underwater videos
No extra housing required
Heaps of mounts for any application
ConsCharge and use - no charging whilst recording (I know most cameras are like that)
No ability to turn sound off
Camera creates a standard 1080 file and a 460 file at the same time (for posting on YouTube) I my opinion this is a complete waste of time and disk space
Battery is not replaceable (Biggest Con)
Would I buy one again - NO
Why - well the battery has had it and the camera doesn't do what I want it to do and how I want it to do it.
