I'm going to buy a 15 MBP to upgrade from my current 13. I really like the anti glare screens and quite like having a cd drive even though it isn't used that much. What would you guys do - go for these features on an older computer or change with the times and get the newest technology? I work in finance so it is just a business computer, nothing fancy. I'm worried that if I buy the 'traditional MBP now that it will seem outdated very soon.
