It's sort of weird to separate them out. Laptops were for the early adopters. They make up the first 10% of the area under the curve from zero to the adoption plateau of general purpose computing devices.
pads will constitute the renaining 90%. They are bringing a useful machine to the $500, $400... even $100 market. They, like cell phones did for cameras, are what will make the technology ubiquitous.
So, it's hard to say what is "more revolutionary". If you are more concerned with the invention of the basic concepts, the PC is. If you are more concerned with what were the last big changes required to unleash the technology in a ubiquitous way, pads are.
