bchen112: You have nothing to worry about. Even if there is some pressure on your keyboard, it won't hurt anything because the pressure is distributed between so many switches.
If you took a few springs out of a mattress and stood on them, you could damage them. But when you lie on a mattress full of springs, your weight is evenly distributed over all of them, and the springs hardly move.
Try this:
1. Disconnect your keyboard.
2. With your open hand, press down on the keys.
You'll see that you can hardly press it at all, because all those springs are sharing the weight.
I've carried MK's around in backpacks with all kinds of stuff, and have never had any problems. As long as you use a sleeve to prevent scratches, you'll be fine. Cheers, A.
