I have currently an MBA 13". I want to buy a new Macbook with a better screen. 95% of what I do with my Mac is watching movies/TV and surfing the Net, mostly on the sofa. So my laptop is really a laptop. I carry it around in the apartment but rarely outside. I surely would be OK with a Macbook Pro 13" but could also buy a 15", money is not the issue. I just oner whether 15" really gives a noticable better viewing experience and whether that will offset the disadvantage of additional weight and size. I know, thats all subjective so I am interested in the experience of those that had both.
