Does running MacBook Pro in clamshell mode cause any damage?

I have the newest model Unibody MacBook Pro and I've been reading mixed opinions on whether or not it's safe to run my MacBook Pro in clamshell mode or not. I'm thinking of getting an Apple Cinema Display but want to know if clamshell mode causes any damage whatsoever.

"I have a friend who runs a studio and keeps a Macbook Pro closed and I haven't seen a problem with this.

The only vents are at the back.

However, I can say from my friends one that the heat pretty much evenly spreads out across the chassis."

"I have a 2012 15"" MBP (Non-Retina) that I use in clamshell mode most of the time. I've been doing some video encoding for a project I'm working on and was worried about head since when I'm encoding all processors are running at 100% and the fans are going full blast. I purchased iStat Menus to monitor the temperature and I found that while encoding with the screen fully open and processors running at 100% I was running at a steady 117ºF… while encoding with the screen closed and processors running at 100% I am running at a steady 122ºF. So, yes, it's running a bit warmer but that could probably be attributed to the fact that the GPU is powering a 27"" Thunderbolt Display instead of the built-in 15"" display.

My feeling is basically that Apple has built the clamshell-mode functionality into the machine and I don't think they would have done that if it was going to cause problems. I know that there are a lot of people who run their MBP's in clamshell mode (myself included) and I have yet to meet anyone who had encountered a problem doing this."
