Hm I guess it just comes down to preference as the ReplayXD1080 is $300 and has a hardwire switch available for $100.
GoPro Hero 3 Black comes with a really cool WiFi remote which also hooks up the iPhone to view.
I think if I'm planning on mounting it primarily on top of the backseat area the cameras would be both out of the way enough. The Replay camera is definitely sleeker looking IMO but the GoPro doesn't look nearly as bad once it's out of that plastic case.
Any more suggestions are appreciated of course!
