nothing i've seen from meedio suggests its better than RR or frodo. It does have a huge following and LOTS of plugins but most of the stuff isnt car-ready. I use it for traffic, weather, and movie listings mostly.
From my point of view, its more ready for remote then anything else, all the Meedio can be controlled with five buttons only, what is a holy grail for me since I have no touch screen, but use original steering wheel remote, it has a TV / FM integration all front ends can only dream of, its got wether and traffic info implementation... and its stable. Does it answer your questions?
