Hey f1anatic, thanks for the input. Let me clear up a few things I may have been ambiguous on:
I didn't want to leave the tablet hanging, and I guess my definition of portability is a bit vague. The initial thought was that it could be mounted the same as a 7" lcd screen like yours. At least I think this one is yours
EDIT: Woops, got the link from your official CarPC thread, but it belongs to Stage3Legacy
With similar dimensions, wouldn't the tablet also fit?
It's really all I'm looking for, at least as a starter CarPC system (I may be able to get the tablet for free through work. They'll let me play around with it.)
But If I could get that form and fit with just basic android functionality, methinks I'll be good. At least for now.
