When I first got into this journalism lark in the late 1980s, the exploding nature of the personal computer market would force the hand of IT companies to reveal products far in advance of their intended launch date. Such was the race to give the appearance of being cutting-edge, they sometimes found themselves announcing products that existed only in diagrams on a boardroom flipchart. Surprisingly often, nothing ever came of these vapourware products: the engineering challenges of their mass-production proving uncompetitive and their technologies absorbed into other projects or sold off by liquidation administrators.
