Hi Guys I know this question has been asked before, but I wanted to see if anyone with similar scenarios had upgraded recently. I have a almost 5 year old (march 2006) Rev A 2.0 GHZ Core Duo Macbook Pro, with 2GB Ram and 320GB storage. It has taken a beating but this machine is still going strong. I am currently tempted by a educational department promotion which gives us 1 yr no 0% APR on a new computer purchase, thinking about going with a core i5 or core i7 15" MBP. My usage is moderate, I do heavy browsing,email,chat as well as moderate photoshop usage and multitasking. What is your suggestion, should I hold off for another cycle?
