Why comparing to the 12.4 6S Pro and not the 14" Pad 6 Max from Xiaomi ? I know you tested the 6S Pro but come on. 609 grams is way lighter than the 750 grams of the Pad 6 Max or the 718 grams of the S10 ultra (14'6" though). It's almost as light as an iPad Pro 13
The Pad 7 Ultra is about to debut alongside the Xiaomi 15S Pro. Both will be powered by the self-developed Xring O1 SoC, and the company has now shared more details and pictures of the flagship tablet.
