We Might Need to Start Calling Them "Big iMacs" Apple’s latest all-in-ones are bigger, brighter, and simply the best yet. Glancing at a spec sheet, Apple’s latest iMacs might seem like run-of-the mill product refreshes. Sure, there’s the requisite processor bumps and storage updates, but an iMac’s an iMac, right? Ah, not so much. When you see these machines in person, their differences are much more apparent, striking even. The new line-up includes four new machines–two small ones and two bigguns–and we had the chance to review one of each size for this article. The most obvious improvements are the larger displays. The early 2009 iMacs were available with 20- or 24-inch screens, but Apple’s newest models rock 21.5 and 27 inches of display majesty. These changes are important in a couple different ways. First, the new models have native 16:9 aspect ratios: 1920×1080 for the 21.5-inch model and 2560×1440 for the 27-inch iMac. Home-theater geeks will notice right away that this new aspect ratio looks demonstrably different from the 16:10 proportions of the previous generation of iMac screens. Essentially, the new displays are a bit “squatter” than previous models, but fall in line with current HD standards. It’s tough to say if that has anything to do with the possibility of Blu-ray drives eventually making their way into the Apple stable, but it’s good news for anyone who watches HD content on his or her Mac. The 27-inch model is gunning for a spot on your living room wall. The new larger screens also feature LED backlighting.
