In the past, RPI laptops have come with Photoshop Elements. I can’t guarantee that this will be the case for Fall 2011, but I imagine it wouldn’t change much.
I’d like to make you aware of student discounts for software. Through the Campus Computing Store, you can get software suites (including a variety of Adobe packages) for VERY discounted prices. I recently got Adobe Design Standard CS5 for a few hundred dollars.
