For all of us Delphi zealots, it looks like a dream come true. Delphi's amazing VCL (the visual component library) has become the CLX, which you can use to write applications that will run on either Windows of Linux.
For those of you who don't like Object Pascal, Kylix will support programming in C++.
Michael Swindell, Director of Product Management - Linux Tools has also said:
We are sensitive to open source licensing issues and are spending great efforts to make sure that Kylix will meet the needs of both open source and proprietary developers to the best of our ability. I'm not promising GPL, but what I am promising is that open source has been an important consideration in the Kylix project from the beginning and will continue to be.
Before you discard this as a meaningless bit of marketing speak, you might like to read the Interbase Public Licence, and remember than Interbase is owned by Borland.
It is going to be interesting to see what impactg this has on the penetration of Linux on the Desktop. I see a lot of Delphi companies very excited about this, so the demand is there.
