Kate owns a Messagepad, but doesn't seem to use it.
Year of feature (shown above)
i think that is a MessagePad 110 or 120. The MP100 was more square!
She uses it. It can be seen when she is doing preparations for the hack battle with Crash Override that there is something written on it
Kate doesn't pick it up, but later in the film Nikon looks like he was using it. He wrote something on it as he was figuring out when the worm would end it's run.
I wouldn't have used mine either if I owned one around the time it was released.
