In-car tablet infotainment

I've been seeing quite a few custom tablet integration solutions lately - mostly with iPad minis and Nexus 7's. I'm torn between thinking it's really cool or just too much. Now if a vehicle OEM was doing it out of the factory, maybe that would be more appealing.. Just a thought I got after seeing the new QNX platform at CES. What if the tablet was removable - kind of like a smartphone dock for tablets!
