Hi, I've got a 3 week old Macbook 13 (2Ghz model + 4GB RAM). I've noticed on occasions - usually while it is on my lap - it gets really hot to touch - is this normal and is there any way I can monitor the temperature? It is usually when I am doing more intensive things (video editing + various other apps open) and obviously the aluminium frame body conducts the heat well. If I can monitor the temperature, what are the normal operating temperatures? I'm new to Macs and there probably isn't a problem, just want to check!
