The demo gave a fore-sight of how working lifestyles would be in the 21st century with e-mails, word processing, hypertext, the mouse and video conferencing. This particular demonstration needed a lot of assistance from the support staff and also a mainframe computer that had the facility of time-sharing. It was found that all of this was way too expensive for businesses that operated individually in those days.
