Another thing to consider is the new Adobe software rental program. (I forget the name).
They have a $30 per month teaser rate for the first year of the program ($50/month starting the 2nd year) that lets you use a wide variety of high end Adobe software, photoshop, premeire pro, just to name a couple. If you are a heavy user, its a good deal. If you are a infrequent user, its likely best to use a lighter software version.
