Thanks Dan.

I didn't know because I don't have a SGTab, but I'm considering one.
I missed out on the Telstra $299 web-special, and I'm currently divided because I want an ASUS Transformer or a compromise in the middle (like the new SGTab 8.9").

You know why, like I told you, I will put the amplifier under the front-passenger-seat and hook it up to the device which will become the centre-console (not dash) and double up as the GPS receiver. And possibly make a good mobile companion (to my i9000/N900) or home entertainment (competing with my PS3).

Here's a picture of my '01 Corolla, it has the best spot for the tablet/gps/music/videos. The inner area where the current stereo and the empty pocket will fit a 7" tablet perfectly.
To fit in a 8.9" Tab, I'd have to cut into the borders of the outer-plastic, ie a whole lotta cutting, should I?
