Canon PowerShot SD20
This camera is small enough as to not make a noticeable bulge in your suit pocket or even your pants for that matter. It is a 5 megapixel digital camera that is now very cheaply priced because it came out a few years back. The camera's lens create quite pleasing images. Of course they can't quite compare to the quality found from SLR cameras, but for most college or day to day events this tiny camera is much easier to carry around.
