So excuse my ignorance, but I was in Best Buy testing the retina MBP. I have some interest in purchasing it, but I noticed in the resolution preference settings, I couldn't get the machine to go to 2880 x 1800. It was only you know, Large Text, Recommended Setting, or More Space. And the resolutions they showed didn't seem to show an option for 2880 x 1800. The "More Space" gave I think 1920 x 1200 or something? How do you make it 2880 x 1800? Also, did anyone switch over from a Macbook Air 13"? That's what I currently have, and honestly, my eyes strain to see the text when I'm writing for a long time in MS Word or when I'm reading a lot off the internet. I can enlarge the text, sure, but then they seem a bit blurry and they strain my eyes that way. So retina sounds like it might be the answer? Maybe even the 13" retina when/if it's released? So would the retina-ness of the MBP line help my eye strain? I already have had my eyes checked out and wear glasses. So it's not me, per se. Thanks in advance.
