I hear ya. At the moment the focus is just getting all the features in and the bugs ironed out but once we hit beta you can count on porting to Linux and OSX being a priority. A conservative estimate I'd say is by the end of the year.
Have you tried any of the recent versions in a VM? There were some issues with how the GPU was initialized for background compute and rendering that were changed up to (hopefully) facilitate cross-platform support when run on a VM. Let me know if you can manage to get it running via any kind of virtual machine because that would be useful to know and report to other users as well :)
