If the iPad 3GS was a smaller step forward, the iPad 4 was a big one - it had a new, sleeker, more modern look, and massively increased the pixel count while keeping the almost same size display size (this was the first Retina display). It was the first iPad with a front-facing camera, the first iPad with some level of multitasking, and one of the most significant iPads Apple has ever made.
