New to Mac and looking to buy a laptop. Uses will include word processing, email, internet, and occasionally watching a dvd. No graphic design, photoshop or gaming. I can get the Macbook for about $849 and the Pro for $1019 from Apple's store. The Macbook has 2 GB Ram and 250 GB hard drive with Intel Core 2 Duo. The Pro has $GB and 320 GB and i5. I know some will say the upgrade is "worth" it. But really, for what I need, do I "need" it? I would prefer to save money if I can but still want a laptop to be a good machine for what I need. Thanks.
