depending what mount you chose. On some the table/arm are easily removed with no tools. Yes the mount is still there. On others its is slightly different but the same concept. But in both cases it is no tools required.

The one I installed the seat never had to be removed. It had to be unbolted but not removed.

Just a thought... To make it lighter for moving around, and to maybe help provide ventilation for the laptop, you could always drill several holes in the top piece. Just a thought, and it might hurt the aesthetic. Very cool though.

the final version might be aluminum, but drilling the top full of holes sounds like a "cool" idea. Thanks Doug!

If you drill the top full of holes, i'd definetly bend some stuff down the sides to support it.

I would also consider some way to hold the laptop, via extra rubber sticky feet or physical sides.

Wouldn't want the laptop falling off.

I do like the idea of holes for ventilation. Although it would be nice to have no holes in it at the same time so you can use it as a writing pad.

ya, I just bent the front on this one, but the final will have a small lip on the front and sides, welded at the front corners to add strength. I also have these sticky cell phone holders for the dash that I put underneath to hold laptop and absorb vibrations What I am planning on doing for mine is hard mount the mini port replicator for my thinkpad on the table. that will hold the laptop securely and will make it easy to remove laptop when leaving vehicle (don't have to unhook any wires). Also need to hardwire a dc-ac converter and put a 110 outlet in the center console.
