Programs that I must have for my iMac...

I was looking at the apple website, wondering what was available like Photoshop for me to do neat stuff..

Look at these...

Comic Life Deluxe Edition only $29.95!!! I will be buying this one.

I'm a little curious about this one...Adobe Photoshop Elements 6 for $89.95. I wonder if it's like normal basic Photoshop?

And last, but not least....Aperture 2 for $199.00.

Has anyone used any of these products?
