In my experience, it really really is. I had to develop a simple GUI application for extracting a few hundred GBs of image data from a complicated folder structure created by an automated microscope. It had to run great on windows and mac os (and linux of course won't hurt, just in case, as it has some desktop use in academia). I developed the tool in linux (xubuntu), and: - Compiled it without change on windows (Just press that green button). - Compiled it with one single change on Mac OS X (some cthreads library import missing). I finished the project from design to final approved product, INCLUDING learning the language as we went, in 80 hours. I find this pretty amazing.
