 Last year, Apple brought a super sharp, awe-inspiring 5K display to the 27-inch iMac. It was the best screen we'd ever seen in an all-in-one PC, and moved the company closer to putting retina displays on every Mac. Now it's 2015, and Apple has almost hit that goal with the launch of its latest iMacs. The display is even better, and now there's a smaller 4K version that looks fantastic in its own right. On the outside, Apple's new iMac sticks to the same aluminum and glass design it's had for years now. The ports around back are also unchanged. Two Thunderbolt 2 ports, four USB 3.0, an SD card slot, headphone jack, and Ethernet. There's no USB Type-C, which is a real pain since you've got to reach around the iMac to plug anything in, so a reversible plug would have been real nice. But then you get to the screen, and it's crisp and possible to distinguish pixels. There are 14.7 million pixels on the 27-inch model, and 9.4 million on the new 4K version. At both sizes, the new retina iMacs can display a wider color palette than before, making everything you see more vibrant and true to life. It's not something you'll always notice in daily use, but professionals will definitely see the difference. These new iMacs are also a perfect way to watch and edit the 4K video clips from your smartphone, say, an iPhone 6S Plus, which is what we used to shoot this entire video. Inside, both iMacs feature upgraded, faster chips. Intel's new Skylake processors power the big one, though not the 4K model. Don't be too worried about that, since both machines are plenty powerful. The smaller one lacks any sort of dedicated GPU, so it won't do you much good for gaming. And whatever you do, make sure to upgrade the hard drive, because Apple sticks a painfully slow 5400 RPM hard drive in the cheapest iMacs, so moving up to a Fusion drive or SSD is essential. Along with the new iMacs come new accessories. Apple has redesigned its Magic Mouse, Keyboard, and Trackpad, and all three are now rechargeable. The Magic Trackpad 2 has seen the most changes. It's bigger, it's white, and now supports Force Touch, just like Apple's MacBooks. If you push a bit harder on the trackpad, you can look up words in the dictionary, or see addresses in maps, or preview links. It's useful stuff, but it's also the kind of thing most people will probably just forget about. The keyboard and mouse have seen slight design changes, and you'll have to charge the ladder by plugging a lightning cable into the bottom. It's kind of weird, but thankfully all three last a month once they are charged. So those are the new 5K and 4K iMacs. They're super powerful, and both have amazing displays. These are the best iMacs Apple has made yet, but they're also not exactly cheap. You'll spend at least $1800 for a 4K model that works the way you want it to. $2000 if you want something really great. And the bigger one also climbs way over $2000 once you add a Fusion drive or that new Magic Trackpad. But those are prices worth paying, because Apple's iMacs were already the best all-in-one PCs when you factor in design, performance, and customer support. Now they're far and away the best looking ones, too, and they come in two sizes.
