I rather like the idea of an oven with internet access. It probably exists already and I bet there's a market for it. People could download recipes, or instructions for bringing the work of outside caterers from delivery box to their own table. People could instruct their home oven 'I'm setting off from work now, so switch on and preheat' or 'switch on to cook the dish I left inside, with you set to "chiller" mode to keep my food fresh.'
