Hi, I bought a 13" Macbook Pro last April at the refresh. I absolutely love it but lately I have been feeling the need for a more powerful machine. I am a 15 year old so money isn't too easy to come by but I have managed to save up for an entry level iMac as my main machine. I would go and do this now but what do I do in less than three years when I go to college? I want to buy a nice 15" MBP right before college with the help of the sale of my current MBP. I don't think that an iMac is a great college machine so I think I may sell that right before also, but is worth only having it for a little less than 3 years?
