Laptops/cell phones with built-in headphones

Come on, you want me to carry around a laptop AND headphones? I need to throw headphones in my pocket along with my cell? You're supposed to be convenient and portable. Even simple, crappy retractable headphones would do the trick.

Secondary option: make it possible for me to listen to my music as if listening on a cell call, as an alternative option to the external speakers. Would make many a bus ride more enjoyable.
