I realize that I may be approaching this from a very PC-centric point of view, but when i purchase gear, I always try to make sure I have the best, or at least close to the best. If apple is smart, then they'd just use vector graphics and everything would scale appropriately (ala Windows 8).
I don't *need* a retina, because you're literally quadrupling the number of pixels while keeping everything the same size (which to me defeats the purpose of a high resolution panel in the first place). Also, a retina panel would mean increased battery use, dimmer (possibly) screen and be extra taxing on the GPU. I would like at least 1080p because that's when you can have 2 browser windows side by side and not have to keep scrolling sideways (too much) and it's only 1.6 times more pixels vs 4 times more pixels.
Now, with 1440x900, I could just zoom out, but because of the lack of pixels, things will be harder to see because you won't have enough pixels to accurately represent the image.
From what I can tell, the reason people here wouldn't want a 1080p (or 1200p to keep the 16:10 ratio) would be because things would be too small. Which I don't see as an issue depending on how Apple manages that change. Or even better, they should offer a 1200p option so it will satisfy those who don't want the increased battery drain, eye strain, etc. But then again, it's Apple, everything's going to be one size fits all...
