In 1995, IT journalist Don Tennant asked Bill Gates to reflect upon "what trend or development over the past 20 years had really caught him by surprise". Gates responded with what Tennant described as biting, deadpan sarcasm: "Kaleida and Taligent had less impact than we expected." Tennant believed the explanation to be that "Microsoft's worst nightmare is a conjoined Apple and IBM. No other single change in the dynamics of the IT industry could possibly do as much to emasculate Windows."
