Hi there. Question: Which one should I buy, new MacBook 13.3" or new MacBook Pro 15.4"? I'm planning to bring it to office and using it as a my main computer at home. I think processing capacity of both is really no problem(I'm doing PHP programming(at office and home) and some Photoshop, compose music(at home)), but I'm really worrying about is screen size and portability. There are no problem when I'm at office cause I will use external display. But how are the screen size(Is too small to use it as a main computer at home?) and portability(bring it to office 5 days in a week etc...)? * I've never used any Mac and any Laptop before. Any opinions are welcome. Thanks in advance.
