Well, the screen itself looks absolutely unreal. I can completely satisfied with my old laptop's display until I played with this one a while. Now I can't go back.
Just imagine looking out a window, and imagine the depth and detail and fine lines that you can't see on a screen. It's probably impossible to just picture it in your head, but believe me that if you were to see it in person, there is a moment where you just go "ohh... wow."
But enough Apple-swooning on a Google forum - that's not why I'm here. The point is that it just looks *incredibly* better.
And to make one more quick point, I absolutely see where you're coming from when you say that this is just one laptop from one company. However, that exclusivity is very temporary. It doesn't really take a tech pundit to tell you that this is going to usher in higher-density screens on various other laptops from numerous other companies. The point isn't to meet the standards of *one* display (although it may seem like it today), but to optimize the program for a future where a good amount of people will be able to have a significantly better experience. :)
