As a left hander I personally hate pencils. The writing gets smeared and the side of my hand super dirty.
Does my hand crank coffee grinder and french press count? It takes about the same amount of time to grind the beans as it does for a cup's worth of water to get to a boil on the stove.
But more seriously, I'd have to say books. I've tried downloading e-books from our library onto my ipad and just don't find the task of reading a book that way to be at all as enjoyable as a physical book made out of paper.
