Playing Chess against your computer... Tips

Man the computer is GOOD I mean Big Blue thumpped the Human. But the problem is we arn't like computers we are thinking about our day, things we said, did, should have done. So i figure to even the field don't just play the computer, but start up web browser, email, photoshop (very CPU intensive), run calculator, imovie (movie maker on windows), any program you have, etc till you have the advantage. ;)
