I've promoted this idea for a while too, it was in fact a core idea at Phoenix (though I'm a relative newcomer to Phoenix only having been in it 18 months). An all-in-one yet modular computer would be a wonderful system for people, especially if marketted with a range of educational software. Ship it with a good OS (MOS), all basic software and some really easy dev tools (my three-stage IDE idea brought to fruition) and you'd be up to a good start.
