Managing these products with separate OS's and requiring different software for use on both, helps insulate Apple from cannibalization of their own revenue by someone buying an ipad instead of a laptop or vice versa. Part of their pricing strategy with the keyboards & such for ipad is to help ensure price parity between these two platforms, and to disincentize as many as possible from thinking they can get away with just an ipad.
