I have used my MBP in a TwelveSouth BookArc with Apple BT keyboard and touchpad. MBP gets rather hot in spite of being in a ventilated position. You have to leave it plugged in for the MBP to work in closed-clamshell mode. Doing so I think I've cooked the battery. I'm only getting about an hour or so use when not plugged in. And the fan runs flat out. I have since built a desktop with 2x24" screens, SSD+HD and using the BT keyboard and touchpad with it. The MBP is back being used on the road - still need to replace the battery. In hindsight, I should have gone straight to building the desktop and using a ChromeBook on the road. The Mac mini is nice, but think you get better value for money using a standard desktop. As many HNers have pointed out as far as bang for buck goes, laptops are expensive to buy and even more expensive to upgrade or repair.
