Samsung's latest laptops are gunning for the MacBook Pro and Lenovo Yoga.
Samsung's latest laptops are pretty similar, but with two major differences: the Book 9 Pro has more processing power, while the Book 9 Spin transforms into a tablet.
The Spin is a 13.3-inch laptop, while the Pro is 15.6 inches.
Here's a nice size comparison with the two computers closed.
Both machines have Core i7 processors, 8GB of memory and 256GB of solid-state storage.
They've also both got high-resolution touchscreen displays. The Pro has a 4K screen while the Spin is nearly 4K.
The Pro is also a bit thicker and heavier.
My favorite part: the touchpads on these machines feel smooth and responsive, unlike many Windows laptops.
The black anodized aluminum frames also look sleek and feel quite strong.
The chromed bevels around the touchpads are a nice, attention-grabbing touch.
There's also a shiny silver Samsung logo on the lid of each computer.
Each of these machines has plenty of full-size ports. Here's the Pro, which has a full-size HDMI port, USB 3.0 port and USB Type-C port (which supports USB 3.1 and DisplayPort 1.2) on the left.
You'll find two more USB 3.0 ports on the right side of the Pro.
The Spin forgoes the USB-C for a volume rocker, since it has a convertible tablet mode.
Here's that tablet mode in action.
The right edge of the Spin. It has two full-size USB 3.0 ports and a microSD card slot. No full-size SD here.
The Spin's screen flips all the way around. You can use a touchcsreen keyboard if you prefer.
Or you can flip it a bit farther, flat against the back of the laptop, to transform it fully into tablet mode.
The tablet can tell which side is up, so you can hold it vertically as well to see more of your favorite websites at once.
The Pro has a full-size SD card slot. The card sticks out slightly.
That SD card slot is cleverly hidden inside a trap door built into the curved side of the laptop.
One last shot of the Spin.
One last shot of the Pro.
