I do think it's a tad pedantic to enforce a *nix OSs only sort of rule, I think the general interest for tech/computers should be on display period, and trying to draw lines on how that can be shown based on the OS of all things does feel a bit off. It is not in everyone's best interest or desire to run a Unix-based OS and I don't think that should immediately bar people from posting here.
Now I am certainly new here and I'm sure people will disagree with me but this is just my 2 cents
yeah, that's kinda where I'm at with it too, I don't think people should be immediately banished because they chose to put say windows 7 on an old thinkpad instead of linux and take a pic with that
