Hello everyone, I purchased a MacBook Pro back in June of 2009 when I was about to start college. Last fall the display broke, but it was still usable (Long story). I put it up on eBay 2 days ago and am hoping for it to sell between $300-$500 for parts. I was planning on purchasing a new MacBook Pro today. However, I did not think that they would split the MacBook Pro series like they did. The new Retina MacBook at 15.4" leads me to believe that the 13" will receive an update next year sometime. The thought of me purchasing a 13" laptop to have it be vastly outdated in the next year does not sit well with me. Do you think it is worth it to eat the bullet and purchase the 15" Retina or should i go with the 13"? Keep in mind I will be using the purchase for 4-5 years.
