I really want a new Macbook. I have a 12" PB. It is great. Works perfect and still has plenty of power. The thing is, I have had this computer for a while. Should I try to sell it now while I can still get a good price. Or should I just hang on to this trusty machine. I am afraid of being left in the technological dust. I think I can hold on for one more year at least. Should I sell now and buy a new Macbook? If I had the extra cash, I would buy a new Macbook. However, I am broke. Suggestions?
