If you\u2019ve been anxiously awaiting your chance to buy Apple\u2019s new 24-inch iMac, iPad Pro, or Apple TV 4K, the big day has arrived. Apple has opened up preorders for the rest of its Spring Loaded event products at the Apple Store as well as Amazon and Best Buy. \n\nKeep in mind that this is a preorder so you won't be getting your new products straight away. Estimates in the Apple Store are showing May 21-27 in the App Store and June 1 at Amazon, but keep in mind that those are just estimates and could change. During the iMac\u2019s unveiling, Apple said that the Mac won\u2019t ship until the second half of May, but leading up to the preorder, multiple sources are reporting that the iMac will ship on May 21\u2014including Apple's own press release in the U.K., as spotted by 9to5Mac. So it's probably a safe bet that orders will begin arriving by then.\n\n24-inch iMac\n\nThe new iMac 24\u201d is Apple\u2019s first iMac with Apple\u2019s system on a chip\u2014in this case specifically, it\u2019s Apple\u2019s M1. It also features a new design that\u2019s a lot thinner than the previous iMac, and it has a 4.5K Retina display. Color choices are available, but the choices depend on the model you pick. Apple sells three standard configurations, and customization options are available:\n\nThere are some major considerations when picking with iMac to buy. We think that the $1,499 model hits the sweet spot of price, features, and color choices. We have a separate article that goes over the differences in greater detail between the iMacs, so if you\u2019re still trying to figure it all out, give it a read.\n\nBut don\u2019t dilly-dally. Chances are the new iMac will sell out fast, and you could run into delays if you wait to put in your order. During Apple\u2019s recent quarterly results announcement, the company said that it will be experiencing \u201csupply constraints\u201d in the next few months, affecting iMac production.\n\niPad Pro\n\nApple's new iPad Pro comes in two sizes, the 11-inch and 12.9-inch, and is a pretty big upgrade over last year's model. Specifically, the 12.9-inch model has a new Liquid Retina XDR display that uses mini LED backlighting to deliver a superior picture. Both models also have a better front camera and speedy 5G cellular connectivity. Here's how the prices break down.\n\n11-inch (Wi-Fi): $799 (128GB), $899 (256GB), $1,099 (512GB), $1,499 (1TB), $1,899 (2TB)\n\n11-inch (Cellular): $999 (128GB), $1,099 (256GB), $1,299 (512GB), $1,699 (1TB), $2,099 (2TB)\n\n12.9-inch iPad Pro (Wi-Fi): $1,099 (129GB), $1,199 (256GB), $1,399 (512GB), $1,799 (1TB), $2,199 (2TB)\n\n12.9-inch iPad Pro (Cellular): $1,299 (129GB), $1,399 (256GB), $1,599 (512GB), $1,999 (1TB), $2,399 (2TB)\n\nThe 12.9-inch iPad Pro starts at $100 more than last year and tops out at the price of a 16-inch MacBook Pro with 5G and a 2TB hard drive, so it's definitely an investment. But if you're willing to spend the money, you're getting the best tablet ever made, bar none. Its screen, processor, and design are second to none. We've already heard rumblings of supply constraints surrounding the display, so if you want one, you should jump on it quickly.\n\nThe 11-inch iPad Pro is nothing to scoff at, however. It might not have the XDR display, but it's just as fast and capable as the 12.9-inch model. In fact, we think the changes Apple made put it back on top of the iPad Air. \n\nApple TV 4K with Siri Remote\n\nAfter several years, Apple has finally updated the Apple TV 4K, but it's not all that different than the model it replaces. It has a newer A12 Bionic processor versus the A10X on the 2017 model and supports high frame rate HDR video at up to 60 frames per second. Otherwise, it has the same design, storage, and price.\n\nWhat has changed is the remote. Apple has all but abandoned the old remote design in favor of a more traditional approach with a power button and click wheel. However, there is still a trackpad if you want to navigate the old way. It comes with the new Apple TV 4K and the Apple TV HD (which hasn't been updated), and you can also buy it separately for $59.
