Xiaomi recently announced its Xiaomi Book S 12.4”, a 2-in-1 PC aimed to compete with the likes of the Surface Pro X. Xiaomi's new convertible is a Windows 11 on ARM PC powered by a Snapdragon 8cx Gen 2 CPU. Preorders for the Xiaomi Book S 12.4” will be available starting this week on June 30, 2022 with a starting price of €700. 

Early purchasers of the Xiaomi Book S 12.4” can get a few perks. Anyone who preorders the device in the first 48 hours of its availability will get a €100 discount and a 65W charger (via GSMArena).

The Xiaomi Book S 12.4” is a lightweight device built for mobile productivity. It weighs 720g on its own. The tablet supports a smart pen and keyboard, both of which are sold separately. Xiaomi's new 2-in-1 is relatively thin at 8.95 mm (0.35 in), but it's not as thin as the Surface Pro X (7.3 mm (0.28 inch). It's similar in thickness to the Surface Pro 8, which comes in at 9.4 mm (0.37 in).

The Book S 12.4" is Xiaomi's first 2-in-1 laptop. The company promises up to 13.4 hours of battery life for the device, though it does not specify a capacity. Support for 65W charging should help top up the PC quickly, but the fast charger is usually sold separately for €40.

While the Xiaomi Book S 12.4” competes with the Surface Pro X in several areas, it's important to note that Xiaomi's new 2-in-1 does not support cellular connectivity.

We'll have to wait until the device rolls out to see if it competes with the best Windows tablets. On paper, it has promising specs for a thin-and-light device centered around mobile productivity.
