Yet another pen computer bytes the dust. Sony’s Slimtop Pen Tablet was more of a touchscreen device than a pen computer, but it tried to break the mold, yet again. Artists and children may have enjoyed the setup, but it does not really offer much more than getting a tablet peripheral, except that you get to draw directly to the screen. Even then, your hand can get in the way. Microsoft is pushing a tablet paradigm again, so we shall see what comes next in the chain of pen computing failures.
