Who has a stand for their MacBook?

Do you use a stand for your macBook? If so, what kind?

I plug my rMBP into a thunderbolt display when I'm at home. I just got the Rain Design mStand yesterday, now I'm not sure if I like it. Now I'm thinking about picking up the Twelve South BookArc stand, and use my MacBook in clamshell mode to create more desk space. Especially now that I have the thunderbolt display I feel like I have plenty of screen real-estate without the macbook display.

What do you guys use?
