i never seen this product but i dont think you can smash it on the ground 10x per day...
everything gets scratches - if this thing would be realy immortal it would be used as a space shuttle
i think it survived some falls and is pretty scratch resistant but you cant smash it with all power on the ground without having to worry about it ...
i remember the time a friend said his iphone4 would survive any fall - than he dropped it from 1m and it got crushed

(this should tell you not to drop/smash something just to show you can unless you realy want to break something)
