Apple is bringing more of its iMacs, including the 21.5-inch machines, into the high resolution future.
In a press release today, Apple made several notable announcements in regards to its iMac lineup. First and foremost, the 21.5-inch iMac now has the option of a 4K Retina Display, which uses the same technology as the 5K iMac which was introduced last year. While there are still a few lower-end 21.5-inch iMacs with 1080p displays, this represents the first time that a high-resolution display will be available in the smaller Apple all-in-one.
Secondly, the entire lineup of 27-inch iMacs now features the new and improved 5K Retina Display (more about those improvements later). While there was already a lower-end 5K iMac that came in at just below $2000, today's announcement means that you can snag a 27-inch 5K iMac for $1800. It is, of course, stripped down a bit in terms of processing, graphics, and storage hardware, but it still gets you that glorious 5K display at the lowest price so far.
Also, Apple has apparently improved upon the color reproduction technology inside of these 4K and 5K Retina Displays, saying simply that the new displays "feature a wider P3-based color gamut that provides a 25 percent larger color space." While more accurate displays are always appreciated, it's hard to say how much of a tangible difference this new tech will make for people doing critical color work on their iMacs.
Lastly, the company introduced new versions of their iMac accessories, including a new keyboard, mouse, and trackpad, all of which feature internal batteries which can be charged with a Lighting cable. The new trackpad also features the same Force Touch technology found in the Macbook, which provides a more tactile way to interact with content on the screen.
All of these new iMacs and accessories are currently available to purchase directly from Apple.
