The Predator Triton 900 is a rare fusion of the popular gaming laptop and 2-in-1 convertible laptop categories. However, by no means is it light or thin, and its hinge doesn't rotate 360 degrees the way a normal 2-in-1 would. Instead, the hinge acts as a fulcrum, allowing the display to slide forward and cover the top of the keyboard. Acer didn't announce specs or pricing for the Triton 900, but given its pedigree, we expect it to be one of the most powerful (and most expensive) gaming laptops you can buy when it eventually goes on sale.

Acer claims that its Swift 5 is the world's lightest 15-inch notebook. Weighing in at 2.2 pounds, it is quite portable, and thanks to extremely thin bezels around the screen, it's not as bulky as you'd expect from a desktop replacement laptop. Neither is it flimsy, thanks to a chassis made out of magnesium-lithium alloy. The Swift 5 uses Intel's eighth-generation U-series Core i5 or Core i7 CPUs, which are primarily designed for energy savings instead of computing power. That's a good thing if you're using it away from an outlet, but you wouldn't want to use the Swift 5 as a multimedia editing platform.

The Asus ZenBook 13's main claim to fame is a 95 percent screen-to-body ratio. That means there's virtually no border around the display, and the pixels almost seem to drip off the edge into thin air. It's decidedly futuristic and quite unique, even in a sea of other ultraportables whose manufacturers have caught thin-bezel fever. While those thin bezels make the ZenBook 13's chassis incredibly compact for a 13-inch notebook, there's still enough thickness to pack in some seriously powerful components for an ultraportable, including an optional Intel Core i7 and Nvidia GeForce MX150 graphics chip. Asus also refreshed its larger ZenBook 14 and ZenBook 15 laptops, giving them the thin-bezel treatment as well.

The Asus ZenBook Pro 14 is the second laptop from the Taiwanese manufacturer to sport a touchpad that doubles as a second display. Asus calls this feature the ScreenPad, and it has made some key improvements with the ZenBook Pro 14. For instance, you can now toggle between using the ScreenPad to control the mouse cursor and using it to tap on-screen elements the way you might if you've ever used a Windows touch-screen laptop before. Many of the ZenBook Pro 14's other niceties—like an Nvidia GeForce GTX 1050 Ti graphics card and a superbly rich, colorful main display—are shared with its big brother, the ZenBook Pro 15.

Dell's first premium Chromebook, the Inspiron Chromebook 14 2-in-1, makes the argument these internet-based laptops are useful to grownups, not just elementary school students and college kids. It sports features like an aluminum chassis, a 360-degree display hinge, and a built-in stylus you'd normally expect to find on premium Windows ultraportables. Inside, you'll find an eighth-generation Intel Core i3 processor instead of the less powerful Pentium and Celeron processors that usually power sub-$500 Chromebooks. Perhaps best of all, the Inspiron Chromebook 14 2-in-1 is priced at $599, far more affordable than the Google Pixelbook, another premium Chromebook that starts at $999.

The Yoga C630 is the first laptop to run Qualcomm's new Snapdragon 850 CPU, a variant of the company's smartphone chips designed specifically for laptops and other large devices. On the outside, this PC sports a pleasingly premium silver finish, and its hinge lets the screen rotate 360 degrees so you can use it in Tablet or Tent mode. But what we're most excited about is getting a performance boost from the Snapdragon 850. Current laptops with Snapdragon processors are sluggish, although they have excellent battery life. If the Yoga C630 manages to have both, it'll be an essential part of frequent travelers' gear bags.

With a revamped hinge, an integrated stylus, and a sleek design, the Lenovo Yoga C930 2-in-1 convertible laptop promises to be even better than its winning predecessor, the Yoga 920. One of the best improvements is a pen "garage," a small channel built into the back edge that will hold the active stylus when it's not in use. There's also a revamped hinge, which doubles as the laptop's speaker grille and should theoretically result in better sound.

The Lenovo Yoga Book C930 is a futuristic 2-in-1 convertible laptop. But it's so thin and light (0.38 inches thick and 1.7 pounds) that it begs to be used as a tablet most of the time. Besides its resemblance to a feather, the Yoga Book C930's other unique feature is an e-ink display that you can use for typing on the virtual keys or writing with the included stylus. The C930 replaces the original Yoga Book, adding more powerful Intel processors and bumping the price up significantly, to $999.
