okay so I am selling my iMac for something a bit more portable. I am hoping to get around $1500 once i get a buyer. my question is, should i get the 2.0 model, and have money for accessories like a case, mouse, etc, or should i get the 2.4 model and wait til christmas and ask for these things?!? I browse the internet, use itunes, run windows (vista), etc. I would like the benefits of a backlit KB, but would also like to get something nice for my family this christmas what should i do?
