Sorry about that, lads and lasses – you can unpack your bags again – in a stinging indictment of IBM Corp’s failure to get a machine out there in the market sporting a wealth of IBM-developed applications (it is the world’s biggest software company after all, and Apple Computer Inc has a machine out there in the market) the PowerOpen Developers Conference, which was to have held in Boston next week, has been cancelled through lack of interest – and that despite the fact that the developers conferences just held for two of the industry’s more ill-starred operating environments, OS/2 and Windows NT, were by all accounts exceedingly successful.
