I don't have one, but it seems like you would have to squint a lot. Don't see what the point of making everything smaller is, especially if you can't read it.
Just switched to 1900 x 1200 after reading this thread. WoW so much more screen real estate!!
What is the benefit of using 1400x900??(retina suggested)
If you're young with good eyes (like me) 2880 x 1800 is doable. I used it when I had my rMBP.
1440x900 all the time
1920x1200 is still retina (scaled HiDPI mode), 2880x1800 is no more (retina) HiDPI modethen why did you buy a retina display, if you are not using the retina resolution?
if you switch to 1900x1200, is it still retina? i am new to this
2880 x 1800 most time, but after long days I switch to 1920x1200
