If you were thinking the iMac display was lacking, you might not be alone. Apple has taken the next step forward with their desktop machine, bringing in the “world’s highest resolution display”. Not only Retina, the new iMac is going to be Retina 5K. What does that mean, exactly? It’s got seven times more pixels than your awesome HD TV. It’s also only 5mm thin at the edge, and uses a lot less energy than the existing iMac. Less power and more pixels? Yes, please.
