Apple has refreshed it’s entire iMac line. They all sport Thunderbolt 2 ports, and there is now a 21.5 inch 4K display (Starting at $1499), and they have made all 27 Inch Models 5K (at $1799-2299)! AWESOME!
And they have upgraded their wireless keyboards, mice and touchpads with rechargeable batteries with a month life that charge and pair using lightning cables.
The iMacs are pretty exciting as editing machines, especially with Thunderbolt. I would still prefer NVIDIA graphics over the AMD that Apple now uses across it’s line, but they are still good cards.
