Yeah the quest for better digital file manipulation of a large library was driving my decision to save for the upcoming top of the line Kenwood (my Blaupunkt Memphis is horrible in that regard).
But I realized that for a couple of hundred more I could put together a kickin' car PC (I already have the laptop which I rarely use). It'll be easy and cheap later to add navigation, and my minivan has lots of options for mounting with security and cooling in mind.
