Have you seen the number of buttons on a modern rice cooker? Some rice cookers incorporate pseudo-pressure cooking, and some are even genuine pressure cookers. There are also combination convection/microwave ovens, and I love my combination immersion blender and food processor precisely because it serves two purposes in the same space as either one. It doesn't crush ice or blend as easily as the old stand-alone blender I had, but I compromised on features to save space. (It also has fewer parts and is easier to clean than the stand-alone blender or the dedicated food processor I used to have, so convergence didn't compromise usability.)
