If you're going to slim down a tablet you better make the chassis out of exotic or high strength alloys... All these oversized thin tablets are susceptible to bending and eventually the screen pops out.
The Xiaomi Pad 9 Pro is now official, and it's a relatively thin 12.5-inch tablet with a 144Hz display, 11,000mAh battery, and Snapdragon 8 Gen 5. In China, the starting price is about $566, which makes it pretty affordable for the performance-focused specs.
