[QUOTE]\nThe one's I've used where like typing on a mushy spongy balloon filled\nwith mashed potatoes.\n[/QUOTE]\n\n[url]http://www.thehumansolution.com/duraflex-flexible-keyboard.html[/url]\n\nThis one types very nice on a flat tabletop. The key placing and spacing\nis exactly like any standard PC keyboard so there's no learning curve. The\nonly part that doesn't roll is the little box over the top of the 10-key\npad on the right side of it where the USB cord comes out.\n\nThis unit is made for hospitals and industry where they must be subjected\nto high temperature sterilization and flushing with sterilizing cleaners.\nIt's totally fluid proof and inert.\n\nThe keys have a tactile feedback "click" like regular keys you can feel as\nyou press down. Not mushy at all, even though the keytops will "roll" and\nare not that stiff. Touch typing fast is really easy. .
