I have been wanting to switch to mac for a while now. I decided to do so and bought the 2.26 13" Macbook pro. I also use a very fast sony z. I have found the mac sort of slow - like delays in executing programs. When something is running and I open something else there is a delay. I am use to programs just opening and never seeing a delay. I guess what I want to ask is, if I update the ram and harddrive, will this solve the problem or is the processor the problem, because if it is the processor, maybe I should bring it back and upgrade to the 2.53 Macbook. Any suggestions would be appreciate. Despite this, I am enjoying the mac - it is refreshingly different, there is definitely a learning curve, but it is fun.
