leaving macbook on

The short answer is "no", you won't damage the 'book by leaving it on all the time.
Keep in mind that the MacBook can run very warm at times. I would not leave your laptop unattended when it is actually running. Many people that I know, simply shut the lid, and the 'book goes to sleep immediately. Some people go for weeks or months without ever shutting the 'Book off. Your 'Book uses very little power when asleep, and wakes up within a couple of seconds simply by opening the lid. If this is what you mean by leaving it on all the time, then it's very safe to do that, and a good way to use your 'Book.
If on the other hand, you mean powered on, and you leave the lid open, and you have it set to never go to sleep - then, I would recommend not doing that, unless you monitor the temperature.
I have had a couple of MacBooks that will not sleep when closing the lid. They had hardware problems, and were repaired under warranty. Always watch to see that the 'Book actually goes to sleep when you close the lid. (the LED next to the IR port will start flashing after a few seconds, and you can see that the Apple on the top of the lid goes dark.
 
Leaving the LCD on all the time may cause problems, however. Also, you're putting more of a load on the MacBook than would be on it if it were sleeping, so you might be at a greater risk for component failure later on. All in all, though, the MacBook will be fine if you leave it on for a while, just make sure it's not overheating.
Sleeping is almost the same to your laptop as being shut down, so by "on", I assume that you mean not sleeping. As long as your laptop sleeps when not in use, it will be fine.
 
On i mean like not sleeping. Such as leaving it on while i go to sleep. The LCD is not always on, i set it as it turns off in 10 minutes. The only thing im afraid of is that the macbook is notorious for its heat and scared that the heat will affect my macbook and reduce the life.
 
If you leave it on while idle, the Macbook doesn't get warm at all. You can easily test this out :).
 
There are various aspects here. Any part of your MacBook has an expected life, and by letting it run 24/7, you certainly cut into that more than when you turn it off over night. That's simple math.

That being said: I often keep my MacBook running for several days and I haven't run into big problems so far.
 
is it to play music when you go to bed? i have a small apple script which put;s the mac to sleep after 60 minutes, meaning i can listen to itunes while i drift off and not worry about power problems.

pm me and i'll email you the file.
