If you want to get new AT&T Data Systems chief Robert Kavna really worked up, just suggest to him that his succession to Vittorio Cassoni might be likened to George Bush after Ronald Reagan: Computer Systems News tried, and was met with a heated George Bush, no way, I’m not George Bush, no, I’m more controversial, I lack patience, I’m outspoken, I’m frank, I’m very open-minded, but I like arguing and disagreeing and then changing my mind; I like someone to confront me – it’s not a comparison of a Cassoni to a pussyfoot! Sorry they asked.
