As I said, the case for "wireless mouse" is a lot stronger than the case for "wireless trackpad." There's no reason a goddamn trackpad needs to be wireless. It's gratuitous and wasteful.

Technology companies are not simply idle spectators who need to follow the whims of consumers -- they can create demand based on what products they offer. Apple isn't predicting what people want -- in many ways, they're deciding what people want by limiting options. People don't think they want something if that something isn't available.
