I am looking to purchase a new powerbook. I was wondering if it will make a difference to buy it online, or at an apple store?? I am in college and will be using the educational discount. This will be my first mac, and i wasnt sure if i got it at the store if everything (software, programs....) would be updated to the newest versions. Also i am looking at getting the 15", 1.5ghz, 80gig 4200 hd, 128mb video card, 512mb ram (1 stick), and combo drive. I will be mainly using it for ms office (excel, word..), and internet. I would like to get into the photoshop, and web publishing stuff also. I havent really ever done it before and would like to start using those programs. As far as a DVD burner, would an external burner work with the DVD software that comes with the mac? Thanks for all of your help!
