Hey guys, I wanted to make specific questions about these two notebooks. Hope you'll help me. 1) Is a going back from Retina to Matte High Res possible? 2) Is the IPS so better than the Glossy and/or Matte? 3) Which is the most valuable in the future between the two? 4) Is the SSD/RAM upgrade on cMBP easy and fast (I saw 512GB of SSD is just 250-300) 5) Do non-retina things look that better on the regular screen? On the Retina they are blurry 6) Is 1680x1050 way better than the 1440x900? For normal things like reading, too? 7) Which one has the best cooling system? 8) I saw the cMBP has the subwoofer: does it mean the audio's better? 9) Is the cMBP that heavier? 10) Thanks.
