I'm a programmer. I'm not a developer, systems engineer or whatever else it's called these days. I'm a programmer and an anal one at that. I can't stand blurry screens since 98% of my day consist of typing things in different colors as they tend to render in your favorite IDE. So, long story short. I've been using an MBA 13 2011 which now has a battery + cord problem so I thought of just dumping it and getting an rMBP but I really like the 1440x900 native resolution on the MBA. Just as a reference: I have an iMac 5k that works super and I love the retina screen, so I thought I'd buy a new macbook (the 12 inch half baked thing). I did. I tried it for 3 hours. The screen was NOT good. The uneven number of pixels (2304) made it stop halfway up the left side. If you are one of the unfortunates who owns one, check your left hand side of the macbook and you'll see how the screen is uneven. Well, then there was the story with the keyboard but that's just not for this thread. So why did I just mention the above rant? Just to show you that if there's blurriness in setting the rMBP to 1440x900 I will notice it. Please don't tell me to go down town and check it out for myself. I'm writing here instead. So, if you have a definitive experience - and are very particular yourself about the screen - from running the rMBP 13 in 1440x900, please do tell whether or not it's a good buy for someone like me. Thanks.
