On a scale of 1 to 10, I think I'm giving this device a 6 for now... While it's interesting, different and definitely full of potential, it's just not quite there yet. My phone has the highest resolution of any device I've ever owned (2560 x 1440) yet the image doesn't seem tight (even using the focusing wheel) and images are somewhat blurry. A few of the apps suffer from not enough settings. The image gallery app can present a bunch of images at a time (nice), but once selected, you can't get the image to be full-screen. You can still see parts of the images before and after, the image name above and the selection cursor is this big blue dot right in the middle - annoying! You can zoom in and out but it only zooms in its frame not within the field of view. It also has a slide show but you can't change the wait time which is very quick.
Other apps had their own quirks but one of the roller coasters was fun (what I was really looking for). A couple of titles sounded great but fell short. Oh well!
Oh yeah, the Zarkana one was only a short video, however I think Cassiopée is singing up in the rafters from the middle of a flower - hard to tell though.
