>>That question used to be asked a lot, four or five years ago. But, as things have progress, Linux has swept the Unix world by storm and now the question is: "Does that version of Unix run Linux apps?" IMO, it is only a matter of time before Linux replaces all versions of Unix.

There is a funny TV ad for IBM Linux servers where a manager thinks that an entire roomfull of servers has been stolen. Actually, they have all been replaced by a single IBM mainframe running Linux.

I don't think so either. Apparently, neither do many of Sun's customers. Sun is the one feeling the heat from all the migrations to Linux. Even giving away Solaris isn't helping. Sun has no desktop monoply to leverage, and StarOffice isn't pulling folks away from MS Office to SO on Solaris as fast as Sun would like, but it is giving folks a reason to move to Linux. What do you think, five more years and Sun is history?
