So I finally got a Macbook Pro(First Apple computer) and I am ECSTATIC! I just have a few questions. The MBP comes with only 100GB of HDD space. I might need more. So the question is: If I were to upgrade it would it be best to either buy a new internal one? or get an External Drive? The MBP only comes with OS X Leopard. Is it worth the extra $30 to upgrade?(Or save up for Lion?) Here are the specs if anyone is interested. Macbook Pro 15 inch Mac OS X 10.5 Leopard Processor Type: Core Duo Processor Speed(per Core): 2.16Ghz Processor Config.: Dual Core RAM: 2GB HDD Space: 100GB My other question is. This has 2 cores right? Because it says Dual Core? Also will this easily satisfy my needs of typing documents for school, editing photos, music for iPod, and possibly video editing?
