Hey guys, I plan to use a 2009 MacBook Pro 17" for college. I'm currently taking I.T. My question is: Is it too unpratical/unusual to use a big laptop like this? Although the daily job of carrying it is not an issue to me (super lightweight actually). I'm also afraid of scratching the underside; any tips to prevent it? I'll be honest to it; It's my first time to use a Mac OS. What are some essential applications/programs that may be useful? Thanks all.
