Microsoft’s new Surface Book 3 for Business is a detachable two-in-one laptop available with a 13.5" or 15" PixelSense display with 10-point multitouch. The keyboard base and display are made of durable magnesium finished in a platinum color. A keyboard key releases the hinge for removing the screen to use as a tablet. The 13.5" version has a 10th generation Core i5 or i7 processor with Iris Plus or NVIDIA GeForce Graphics, up to 1TB SSD storage, and up to 32GB of memory. The 15" model has a Quad-core 10th generation Intel Core i7 processor, NVIDIA GeForce Graphics, up to 2TB SSD storage, and up to 32GB of memory. Both versions have two USB 3.1 Gen 2 Type-A ports, one USB Type-C, a full-size SDXC card reader, and 3.5 mm headphone jack. Wireless connections include Bluetooth 5.0 and Wi-Fi 6. There are batteries in both the keyboard case and the detachable screen that allow separate charging when using the Surface Book 3 as a tablet. There are two cameras—a 5-megapixel front-facing camera with sensors for use with facial recognition and an 8-megapixel rear-facing camera on the top edge of the back of the display. Both have 1,080p video quality. www.microsoft.com


The midrange Amazon Echo smart speaker is called the Show 8 for its 8" screen, and it’s right in the middle between the 10" and 5" Show models. Like the others, the Show 8 has the Alexa assistant, stereo sound, and a bright display for photos, TV shows, movies, and trailers from Prime Video, Hulu, and NBC. It plays tunes from streaming services like Apple Music and Spotify, and with Amazon Music you can see the album art and the lyrics on screen. Check the weather, traffic, and news from sources like NPR and Bloomberg, and check your calendar with Alexa. For privacy, you can access the microphone and camera off button or use the built-in shutter to block the camera. If you have smart home devices like lights, thermostats, or security cameras, you can use the Echo Show as a hub for the controls. www.amazon.com
