Chinese startup SpacemiT has presented MuseBook — a laptop based on the K1 RISC-V octa-core processor aimed at AI developers.
Although there is no official launch date, it is expected to be available soon at a relatively low price of $300.
About said TomsHardware publication.
MuseBook looks a bit like an Apple MacBook. It has a 14.1-inch IPS panel with a resolution of 1920×1080 and a refresh rate of 60 Hz. The keyboard resembles Windows keyboards, but the special button is replaced by a RISC-V button. It is not yet known what function it will perform.
The laptop weighs 1.3 kg and is approximately 18 mm thick. It has a microSD card slot, two USB-C ports, two USB 3.0 Type-A ports, and a 3.5mm headphone jack. Below are the full specifications of the K1 SoC.

The laptop has up to 128 GB of built-in eMMC flash memory. Wireless network connectivity is available through the pre-installed RTL8852BE-based WiFi 6 module.
MuseBook runs on the Bianbu OS. This is a Debian-based operating system optimized for the K1 RISC-V SoC.
If you wish, you can also install a Linux version of your choice or RTOS on your laptop.
