I mean, you can chisel a brick to make the corners more round and ergonomic. But nobody is going to tell me 700g is light and comfortable. That's still just a brick.
Even the chungus og Xbox controller weighed less at 550g. And I thought that was an ergonomic brick too.
Asus's gaming handheld is polarizing in its unusual design, but the new grips are extremely comfortable. Anyone who has used the new ROG Xbox Ally X once will certainly not want to go back to a traditional handheld design.
