Review

The ASUS Chromebook Detachable CM30 is a 2-in-1 device designed for portability, blending tablet and laptop functionality. It features a 10.5-inch WUXGA (1,920 x 1,200) glossy display and weighs approximately 609g (tablet only) [S1]. Powered by the MediaTek Kompanio 520 CPU with 8GB of RAM and 128GB eMMC storage, it is built for lightweight tasks like web browsing and document editing [S1]. Notably, the package includes a detachable JIS layout keyboard and an ASUS USI Pen that can be stored within the chassis [S1]. Connectivity is limited to a single USB 3.2 Type-C port, which handles data transfer, video output, and power delivery [S1]. The device offers approximately 12 hours of battery life when used with the keyboard [S1]. For users in Japan, it is important to note that the "ASUS Anshin Warranty" (which covers accidental damage for 12 months) requires product registration via MyASUS within 30 days of purchase [S1]. Please verify the compatibility of your specific peripherals since there is only one USB-C port available.
