If Linux, please specify the distro, as that is basically what I am choosing between. I use Ubuntu 10.10 (I generally switch to the development versions of Ubuntu around the second or third alphas), but I am not sure that there is much difference between similar versions of Debian, Ubuntu, Linux Mint (with mostly the same applications, all that would differ would be some customization). I imagine RPM-based distributions like Mandriva, OpenSUSE, and Fedora would be similar.
