What are the specs of that laptop - e.g. CPU type and speed, memory, disk space, graphics card/subsystem? What does she use it and broadband for? Chances are any half decent (and maybe even a not even decent like my mother's!) PC/laptop will be fine for general web browsing etc. If she wants to do multimedia stuff, music/movie streaming etc. then that may be a different matter. Broadband of itself does not necessarily put much load on the host machine's resources.
