I'm thinking about buying a retina MacBook Pro but am also considering Windows laptops since I've been a long-time Windows user. I've found a few laptops with similar specs as the rMBP at the same price but the main difference other than the OS seems to be the display. How do I compare displays between different brands since I can't put them side by side? Is it just the resolution that makes the retina screen so special or is there something else I should look at to compare each one? For example, the Dell XPS 13 has a QHD+ display with 3200 x 1800 resolution, 276 ppi and Intel HD 5500 graphics card. The Lenovo X1 carbon has a QHD 2560 x 1440 resolution, 209 ppi, Intel HD 5500. The MBP has 2560 x 1600 resolution, 227 ppi, Intel Iris 6100. Based on numbers alone, it seems like the Dell is the best screen and the Lenovo isn't far behind the MacBook. Am I wrong? EDIT: Please everyone, don't make this a battle of Windows OS vs. OSX unless it specifically relates to my questions (i.e. I didn't know Windows has trouble with scaling with high dpi). I know this is an Apple fan forum but I'm trying to find a compelling reason to switch to Mac besides the OS, trackpad, etc. The screen isn't my only deciding factor but is a way to differentiate between other similar specs (all have i5 processor, 8 gb RAM, 256 gb SSD).
