I think I have the 6 as well... the keyboard connection to the tablet is not rigid, meaning you need something to support the tablet itself (like the kickstand)... but using the kickstand on your lap is not very convenient, because it does not hold the keyboard at a fixed angle to the computer... and you have to move it up your legs far enough to have the kickstand extend back and still have room on your legs. You can't have the screen be at your knees.

Also, you are limited in the angle you can have the screen. With a normal laptop, you can open the hinge very wide (like 150 degrees or so) so that you are looking directly at the screen when looking down at your lap. With the non-rigid keyboard, you have to have it fairly close to perpendicular (close to 90 degrees) which means you are looking at a bad angle to the screen when it is on your lap.
