2010 will be like 2009. The year of the desktop for Linux will keep on not arriving, but the Linux desktop offering will keep improving incrementally. Windows will continue to stagnate. Mac OS X will continue to innovate and the Linux desktop community will be better at copying the good bits than Microsoft, partly because of less cruft and partly because Microsoft is still trying to get a sense of itself in a changed world. Personally, I write code on all three, have basically the same environment on all three (Vim, Vimperator, bash, GCC, CMake, OpenGL, Cg) and find all three usable for most purposes.
