During the Android Dev Summit 2026 Keynote, Google revealed that detachable Googlebooks are "coming soon."
The initial launch of Googlebooks only included clamshell and convertible models, with no detachables in sight. However, this mention officially confirms that preparations are underway for their release.
The 5 Launch Models
In the keynote, Google described Googlebooks as coming in "clamshell, convertible, and soon detachables," explaining that Googlebook OS caters to a wide variety of form factors for large-screen devices.
The first-generation lineup consists of the following five models:
-
ASUS Googlebook 14: Clamshell
-
Dell XPS Googlebook: Clamshell
-
HP Googlebook 14: Clamshell
-
Lenovo Googlebook 15: Clamshell
-
Acer Googlebook 14: Convertible
Among these five models, four feature a conventional clamshell design, while the Acer Googlebook 14 is the sole model equipped with a 360-degree hinge for tablet mode. While every model includes a touchscreen, none allow you to detach the keyboard to use as a standalone tablet.
"Lenovo Googlebook Duet m" Emerges as Top Candidate
Although specific model names weren't disclosed during the keynote, prior leaks strongly point toward the "Lenovo Googlebook Duet m (13″, 11)," which Lenovo currently has in development.
Codenamed "Sapphire," development records indicate that it is based on MediaTek's "Tanjiro" reference board family. Rather than the originally anticipated MediaTek Kompanio Ultra 910, it is expected to feature the Dimensity CX C10 Max, a minor revision tailored specifically for Googlebooks.
On the accessory front, FCC filings confirm preparations for a dedicated keyboard supporting both Bluetooth wireless and pogo-pin physical connections, alongside the "Lenovo Pen Pro for Googlebook" stylus.
Furthermore, previously leaked renders showcase a kickstand cover, stylus, a Glowbar positioned next to the camera, and a keyboard with a physical switch.
Portrait UI Challenges Ahead of the Detachable Launch
One likely reason detachables weren't part of the initial launch is the lack of portrait UI optimization in Googlebook OS.
Currently, on Googlebook OS, converting the Acer Googlebook 14 into tablet mode allows full-screen apps to function in portrait orientation. However, the desktop (home screen), Overview mode, and the App Launcher remain locked to landscape mode, offering no portrait support.
Since detachable tablets are frequently used in portrait orientation without a keyboard, full system UI support for portrait mode is crucial. Google likely delayed the detachable rollout to polish these portrait optimizations further.
Additionally, the timing may have been adjusted to align with the release of the Dimensity CX C10 Max chip—tailored specifically for Googlebook—rather than reusing the Kompanio Ultra 910 found in Chromebook Plus models.
Summary
At this point, Google has only mentioned that detachables are "coming soon," leaving the exact release date unannounced. Since Lenovo rarely announces new devices in isolation, an official announcement at CES 2027 in January 2027 seems plausible.
Moreover, the arrival of Googlebook OS tablets will place them in competition with high-end Android tablets. For now, users seeking a pure tablet experience will likely lean toward Android tablets, whereas those prioritizing desktop environments and heavy multitasking will find Googlebook OS to be the better fit.
