The MessagePad was a touchscreen tablet and the very first tablet releaded by Apple which ran on a non color Newton OS it was very advanced back in it's day and came with a pen a lot like the Nintendo DS stylus. It was released in 1993 and discontinued in 1997. It's successor is the iPad released in 2010. Many things that the MessagePad could do the iPhone and iPad can't do. An example of this would be making a shape smooth.
