Hi all. I'm on a 15" MBP classic at the moment, and going to upgrade soon. Debating with myself If I should go 17" next time. I would very like to hear from someone who bring their 17" to class every day, or work. Just experience with the 17" usage in the everyday as a portable. Im going to bring it to the university almost every day, and I don't have any problems at all with the 15". If I were to have the 15" it would be the core one. And I have the option of having the base 17" for only $ 300 more. It will give me a lot more screen real space, since I would not upgrade the screen on the 15" to high res. Help me out please.
