If you like Delphi, but also like non-Windows OS-es as well, you basically are going to have to pay twice or more. Each time for each programming environment (be it Kylix, or something else). Freepascal is a Delphi clone, for Win32 and Linux. It tries to do everything Delphi does, but it does not have a real front-end/IDE. Enter Lazarus. It’s not completely Delphi yet, but it’s nice to see how far they already are. Some Delphi code can be used in Lazarus/Freepascal without altering!
If you look at the Project Roadmap, you can see most of the IDE and most of the components are done and working. The rest of it (LCL, the Lazarus version of VCL, GTK, Qt, Win32) needs some more work.
This how Lazarus looks like on my desktop:
Notice the blue and green line just above and below the buttons? Quite neat: they show if components are aligned or not (then the lines disappear)! Borland, did you see that?
