I love it. Anyone who has the nuts to cut holes in their car is totally fine by me.
The compartment looks useful, but I'd probably pick a different setup if it were for a specific purpose like GPS - I find cars that come with factory "navigation" in the form of a rebranded garmin in a flip up look a little bit afterthoughish. I can envision a really cool stealthed slide-out tablet install, though. Maybe I'll have to try something like that
