Joel on Software - The Road to FogBugz 4.0: Part III:

"Q. Was it worth it?

Probably. FogBugz for Unix is about 10% of our sales. The effort to create it was probably 20% above the effort to create FogBugz for Windows alone. A lot of our customers are happier that we run on Unix even if they're using the Windows version, because they know they could switch servers at any time."

Well said. In our design of PDServer we had taken this account. Even though our customers were running Windows and IE, we had designed the application to run on Apache and support other browsers too.

Its always a tough call to make. Is it worth it, to design you application to be compatible across platforms, even though no customers currently need it ?
