Good night guys! My friend is going to the U.S. next week and am thinking of buying the new rMBP. Currently, I have a 2011 MBP . My big motivation for change is the retina display , since I had a big surprise that feeling when I traded my iPhone 3GS to an iPhone 4 . * I do not understand much about resolution and such, but I believe that the higher the resolution, the more things fit on the screen . And this is something that bothers me in my current MBP : the amount of content displayed . For example: I wanted to use the Dock on the left side , but when I opened Facebook in Safari , the side window with updates and chat disappeared ... The chat was minimized at the bottom right ... and that bothered me , cause to use the chat fixed on the side , I had to use the Dock at the bottom , reducing the content displayed vertically ... the MBP 15 " of my friend .. this does not happen with the same page open in both , mine has less content displayed vertically ... however, I believe that this occurs because of the resolution, and not by the physical size of the screen ... * Therefore, I thought the new retina display and resolution of rMPB solve such problems .. content would be more exposed both vertically and horizontally .. ie less need to use the scroll bar (or could have FB chat on the side and the Dock on the side tb ) ... * But reading a review in The Verge , I was confused as to what I had in mind . Follows the passage which I generated confusion : * " In exchange for the slight extra weight over the Air , the 13 - inch Pro offers a gorgeous , 13.3 - inch , 2560 x 1600 display . It's no longer the only beautiful display on the market - the Toshiba Kirabook , the Acer Aspire S7 , the Samsung Activ Book 9 Plus , and a handful of other notebooks offer Equally stunning screens - but it's absolutely gorgeous . It's Essentially taking a 1280 x 800 display and displaying four pixels in each spot , and the result is clear text , crisp lines and details , and the screen you really do not want to take your eyes off . The problem is simple real estate - 1280 x 800 is not that much screen space . I can see more on my 13 - inch , 1440 x 900 Air than on the 13 - inch Pro ( though everything on the Pro is far nicer to look at) . You can Set the resolution to a maximum of 1680 x 1050 , but it makes text tiny squint - inducingly , and since the display can not pack an even number of pixels into que resolution things look a little blurrier as well . And there are plenty of icons , websites , apps and que still have not been updated for this new high- res world , and the things have not been optimized que look pretty terrible. But be all that as it may , I'd trade the Air 's screen for the Pro's without a moment 's hestitation . " * What does this passage mean? The resolution of 2560x1600 or 1280x800 eh ? What does the phrase " 1280 x 800 is not that mach screen space" mean? The exposure amount of content has to do with the resolution or physical size of the screen ? * I would like to better understand this so I can decide whether or not to buy. And sorry about my mistakes in english. Thank you!
