First, I am not a newbie to Macs, or to retina really (I have a iPhone 5), just to the rMBP. This is my 3rd MBP and on the 2nd day of actually using it. I noticed right off the bat that the color saturation and clarity of the screen is great! I don't really regret upgrading. But I am a little confused here. The display defaults to some low resolution which is "best for retina" (I think it's 1440x900). This resolution is fine for just surfing the web but doing anything more involved makes things feel pretty crowded. Why is retina "best" at this low resolution? Is retina on MBP just a gimmick? Are we supposed to keep using this resolution? Usability wise this seems like a downgrade from the 1680x1050 on my Early 2011 CTO MBP. I see I can change the resolution but won't this end up becoming looking bad due to interpolation? Is this still even a problem with modern notebooks? Thanks for your help!
