It's good to see better USB support.
But to me it's still not 'there' with playlist/drive/software issues, small screens, no selection by tag... etc.
I never thought I'd do this, but I'm starting to put together a CarPC instead of waiting for the high-end Kenwood after reading over at TalkAudio.
I've been looking at the freeware front end 'RoadRunner', and it allows 'on the fly playlists', which let you add to the queue of what's playing rather than selecting a song after the current one finishes (besides regular playlists, and all the amazingly easy selection options based on tags not file names). This makes it easy to put a quick list together when starting out that'll last as long as the trip.
The cost was putting me off, but I remembered my barely used laptop, and it will work out to 30% more than the Kenny, and will allow an easy, cheap upgrade to NAV, wireless internet, rear view camera (besides existing movies, ripping, and in-car Dolby/DTS surround, etc.). And the van gives lots of secure mounting options.
Not trying to change any minds, but to me the only real way to manage a big library (if it's in your budget).
