OMG, I just got MediaCruiser setup and played with it and all I can say is this is easily the best frontend there is. It's simple, fast, and easy to use while driving! I've only had a few issues with music skipping. The only other thing I could see making this better without making it bloated like the others would be a day/night gamma setting and maybe a backup camera.
I hope MediaCruiser isn't dead.
