About a week after buying my Samsung Galaxy S (I9000) i noticed some odd pictures showing up in my gallery of what appeared to be screenshots of my home screen. After a little searching, I found out that within this particular handset, Samsung have built in the ability to take screens of your device without the need for rooting.

To create a screenshot, simply press and hold the 'back' key and then press the 'home' key. You'll receive a notification on the handset confirming a screenshot has been saved, along with a shutter sound. The screenshot will save to your phone memory in /sdcard/ScreenCapture.

Unfortunately as the key combination requires the 'back' button to be pressed first, this will often cause the handset to perform the standard back function of any apps you may be using, making screenshots of running programs a bit tricky to execute. I've found that by pressing both keys simultaneously then immediately releasing them (quick tapping both keys), the screenshot will be successful. Not always, but often.
Pressing 'back' in the below app would normally send me back to the home screen, but by using the 'quick tap' method, I can grab what I need:

Will it work with other Samsung models?
Its very possible that Samsung have made similar additions on their other handsets to allow nice little tricks like this one, so it might be worth trying. Similarly, if anyone knows of any other hardware commands that I can try out, I'd love to hear about them.
