I'm currently a grad student and I'm looking to pick up CS5 before I graduate in December. I was looking at a reseller being pimped by my university's bookstore and it seems they have two different versions of CS5 Design Premium for which my student discount qualifies:
Adobe Creative Suite 5 Design Premium - $359.95
Creative Suite 5 Design Premium Student and Teacher Edition - $448.95
Any idea what the difference between the two is and why one is so much cheaper than the other (obviously I would like to get the cheaper of the two, if it's a full version)?
