Apple on Thursday announced a new high-end iMac that features the company's trademark "Retina" screen, packing 14.7 million pixels into a 27-inch display — a massive 5120 by 2880 resolution that the company claims is the world's most high-resolution display. There have been higher resolution screens shown at CES and other trade shows — but it's certainly the highest resolution display available to the average consumer. And at $2,499, it costs less than many 4K displays out there today. That price includes, of course, the computer inside, though the default specs will disappoint anyone hoping for Mac Pro (or ordinary PC desktop) level insides: 3.5 GHz Intel Core i5 processor, 8 GB of RAM, 1TB of storage and a mid-range graphics card. It's clear that the display, which Apple calls the Retina 5K display, is the selling point here, and it could sell very well on that alone. The new iMac is available now. Apple also introduced two new iPads on Thursday.
