Sena has been running a sale on their 10C Evo, so I bought myself one as a birthday present. It's basically their SMH10 with a camera added. The picture quality won't compete with even an average phone camera, but it's reasonably good -- and convenient. I bought it because I often see interesting scenery or a roadside attraction, but don't have the space (or desire) to pull over and get my phone out. I've only used the still photo mode so far. I can't imagine that anyone (even myself) would want to endure hours of video taken while I ride.
The weather in Colorado is incredible today (low 70s) so I took an 80 mile ride on I-70 east of Denver. The photo below (size reduced to be web-friendly) gives an idea of the perspective and quality. It's not something you'd want to print and frame, but not bad either.
