One rhetorical example I’ve used over the years is that a laptop is a lot like a pair of eyeglasses: It’s practical and it’s something most people can’t live without.
But at the same time, it’s an immensely personal choice, combining the sometimes contradictory forces of budget, features and style. Like a pair of glasses, a laptop is often a big part of the image you present to the world, either in meetings, at coffee shops, or in class, so it’s not only about who offers the most widgets for the least money, it’s about which laptop is the right fit for you.
