Exciting news! Adobe has finally made the free 30-day trial versions of their CS4 software (Photoshop, Illustrator, etc.) available on their website for you to download onto your laptop or home computer. If you don’t already have one, you’ll need to register for a free Adobe account, but that’s a small price to pay for a fully functioning copy of Adobe Photoshop CS4 Extended!
You can download the trial versions at http://www.adobe.com/downloads/
