Honestly, the Transformer Infinity TF700 beats both the Toshiba Excite 10 and Acer Iconia Tab A700 for performance, materials and display. My pick would be the Asus Transformer Pad Infinity TF700, Toshiba Excite 10 and in third place the Acer Iconia Tab A700. I still like the Excite for materials (metal and Gorilla Glass) and ergonomics (it's light and thin yet more comfortable to hold and USB is separate from the charging port) and stability, but the TF700's sharper full HD display is a big selling point and it has top notch materials in a thin and light design. The Acer A700 is heavier and feels slower than the Asus Transformer Pad Infinity TF700 and Toshiba Excite 10.
