IT-Director: "IBM informs us that it has over 300 zSeries customers who are piloting Linux. It also claims that a further 400 are likely to get involved in pilots. The zSeries is the current brand name for the S390 mainframe. So we are witnessing a significant interest in Linux from big companies (by and large, it is only big corporates that have mainframes).
To this news, we can add the remarkable conversion of Amazon to the Linux cause."
