Another happy OpenDingux user here. Although I still keep an SD card with legacy Dingux installed (for anything that doesn't play well with OD), and another one with Dmenu (just for lulz), I use OD the most. The deciding factor for me was TV-out. Despite all my fiddling, I could never get it to work on legacy Dingux, but with OD it just works "out of the box" so to speak. Playing games like Giana's Return on the TV from the sofa across the room with the F-16 wireless controller is great!
