I have a macbook late '08 2.0 Ghz . I did upgrade RAM to 6GB and the HDD. Spec wise this computer is 5 years old which is a very long time in computer years. The thing is that I really do not feel it slow at all, it does everything I want. In my previous purchases, about every 3 years my computer would be outdated. Looking at the new macbook pro's, do you think it is worth upgrading now or should I wait until some kind of a new technology breakthrough comes along or an all new designed macbooks (not sure how long Apple is keeping the current design) ? Other than running the latest games, I do not see my current laptop having difficulty doing anything else. I do not work in the graphics intensive fields. It would be nice to enjoy SSDs, USB 3.0 , Wifi ac , and the retina display but I am not sure if it is worth $1300 ! The only thing that bothers me is that my macbook runs crazy hot playing games or ripping DVDs, something like 90C/194F , are the new macbooks this crazy hot too?
