I'm totally tortured with agonizing over Microsoft's Singularity. See, I have a standing moral obligation with myself as follows: If Microsoft ever released a purely Open-Source or Free Software system - as defined by the Free Software Foundation, the Open Source Initiative, or common conventional wisdom - I have said (and will repeat here) that I would download it, try it out, review it, and possibly adopt it, to be treated no different from software from, for example, Red Hat Inc. or BSD.
