Re: Head to head
"A lot less than Windows to Linux as you're not going to have to change all your applications."
My main applications are IDEs, compilers, text editors (code plus LaTeX), MatLab and Mathematica (apart from the browser). All of them available in Linux. The odd MS-Office document I get opens well enough in LibreOffice. In our department people use Windows (7), Mac OS-X and Linux (Ubuntu) roughly equally. I myself have used all three. Despite my earlier struggles with windows versions, I quite like Win 7. For most of my work I prefer Linux.
Just goes to show: OS wars are SO last century
