i've got the gps version, works great never had it in a case and performed wonderfully, grab a 32GB card for it though, the 1080p takes up alot of space. i use the switch inside to do a medium res and a highres setting so its easily switchable and saves some space. only downside is that the editing software from contour is horrible and anything else you use doesn't export the gps data.
You can use DashWare software (Windows) to combine GPS data with the movie, add speed gauges, track maps, altitude, g sensors etc. It is like $49 and works flawless, I created a lot of movies with it and then process them in iMovie or Final Cut, also you can use Adobe Premiere and Adobe After Effects to do even more with the maps, but it gets little more complicated with Adobe, if you lern to use it, you can create all crazy thinks. Me personally I'm ok with gauges and simple maps that I get using DashWare and Final Cut Pro over Apple. I guess there is video edition software included in Windows as well but I have never use it and just stick with what I know. There is a movies here in prior posts that I uploaded so you can see how it looks like. It was like 2 hrs work time to create it.
