Hi all, I am planning to Switch from Pc and planning to buy a MBP. I wanted to know if it is okay to buy the base model priced at 1799 with student discount and the apple care. Should I upgrade the RAM fro 512 to 1G. I will be using it for school and the usual stuff. Would I require a higher memeory. I can't afford to pay more than $2000. Also the reburbrished are only $100 less than the student discount so should I buy a refurbrished or a new one. Need advice.
