Are there any issues (i.e thermal) with keeping the lid closed and still operating the computer?
The large main vent is not affected by the closed lid because it's across the back; you can see it when the lid's closed. Under normal operation it isn't going to be any worse than running a Mac mini.
It's possible that it might get too hot if you are always running apps that keep the CPU and/or disk running hot all the time. Also, you want to make sure that you leave sufficient room around the unit for air circulation, not shoving it into a narrow, tight shelf. Also maintain the gap below the case bottom (i.e. on a hard surface, not on a sofa or other soft padding).Mac Pro, MacBook Pro, iPhone 3GS, Mac OS X (10.6.6), PowerBook G4 15" Al, PowerBook G3 FireWire, PowerCenter Pro, PowerBook 160

How do I wake it up? I power it up, close the screen down and it sleeps. I cannot get it to simply wake up with the keyboard or mouse. I have been able to close the screen without it sleeping occassionaly but very adhoc and not reproducable enough to make this work reliably. Is there another secret to waking it up after closing the screen down?

How do I wake it up?
Normally, this is not supposed to be a problem. If an external USB keyboard is connected, pressing a key should always wake up the Mac right away. If it is a wireless Bluetooth keyboard, it should still work, unless you have disabled "Allow Bluetooth devices to wake this computer" in your Bluetooth/Advanced preferences.
If there are no external input devices connected, there's no way to wake it other than cracking the lid open a little to press a key.

I have an external USB keyboard and mouse, and neither moving the mouse nor typing on the keyboard wakes it up. I just have to keep playing with it until I get it to awake when I close the screen...very anoying. I thought there might be another setting that I was missing. Any other suggestions?

For the computer to operate in closed-clamshell mode with an external monitor, keyboard and mouse or trackpad connected, the computer must also be running on AC power. It won't wake if it's running on battery power.

Having the computer with the lid closed is dangerous cause even when just browsing the web with flash content it starts heating up and I've heard about casess of melted displays. Besides, the wifi strength is reduced and you can't use the keyboard and the trackpad.
So, for Lion users, it's possible to just use the external display with the lid open:
1. In Mission Control Preferences activate one Hot Corner to put the display to sleep.
2. Connect the external monitor and plug in the power source to your computer.
3. Move the mouse to the Hot Corner to put the display to sleep.
4. Close the lid and wait a few seconds.
5. Open the lid and voila!
