Sleep mode rant!

Why ... I ask.. WHY would I want the power button to do anything else except turn the power off? The sleep button should be for Sleep mode (or crash mode as I like to call it) and the Power button should POWER DOWN!!! Laptops NEED to be powered down. They are not made to run all the time, they need to cool down and be put away from time to time and you should not leave them in sleep mode for weeks at a time. They do not have the big powerful fan your desktop does. I realize a computer in sleep mode supposedly doest generate as much heat, but sleep mode is still completely unnecessary. If it takes your computer too long to start up then consider taking proper care of it.
