I have a 1.67 G4 Powerbook with 2gb ram which seems slooowww these days and I am thinking of upgrading to the macbook pro core 2 duo. I can't decide between the 2.16 and 2.33 models. I use some cpu intensive applications and I also have a 30 HD Cinema Display. I'm still leaning towards 2.16 for the following reason. 1. I upgrade my laptops every 2 years or so and 2.16 makes upgrading easier later on 2. Specs look almost the same. I will upgrade the ram after I purchase The price difference is pretty substantial IMO. What do you guys recomend I do?
