Hey so I a currently using a late 2008 MBP 15inch with 4gigs of ram and 2.4 core2 duo. I bought it when it first came out so it is almost 5 years old but still running alright. It does freeze and the hinge is messed up and creaked screen but still works haha. Trying to decide if I should get the new retina 15 but have a few issues. First is which model to buy. All I use my comp for is school and internet but no gaming at all. However, money isn't really an issue so I figure I should upgrade at least the cpu but should I do the ram as well? And then theres the discrete gpu, I know I don't use games but is there any other reason why it would be necessary to have it? Lastly Im betting they will change the form factor to a 15in "Air" version next year so I hate to buy a new retina if it is going to be a completely different design in a few months. My current pro is working alright but the lag, cracked screen etc is starting to get to me haha.. Any advice would be appreciated edit.. Also with all of the problems I have been reading about on here, if i do decide to get one should I wait to see if apple acknowledges it or maybe a newer batch?
