I jumped ship from Microsoft when Vista came out, switching to Ubuntu in 2008. It was good enough for mainstream production use then, albeit with some warts - but it was already a hell of a lot more polished, functional and user-respecting than Vista. Ubuntu has continues to improve in polish, stability and usability since then. There's no reason for you not to start making the jump now. My recommendation is to start by replacing the applications on your Windows machine with cross-platform FOSS equivalents, if you haven't already. That way, the OS transition will be a lot easier because you will already be familiar with the software.
