You don’t need to have a fursuit, fursona, go to cons or anything else to consider yourself a furry. If you enjoy furry content, or intelligent animals in general, that’s more than enough. And even then, you are free do define you as one or not.
As a mostly windows user, I’ve tried a few times, using various distributions. When buying my last pc and installing a popular linux distribution, it did not recognise my network card at all. Researching online told me I had to compile the drivers myself, since my distri did not have any shipped with it yet. …which is pretty hard, having no internet access because of the network card not working.
For non-tech users, I feel like some parts are still pretty hard to diagnose. If an issue arises you mostly have to touch the command line and I can understand people being scared of it, having to edit plain text files, or type and enter commands that aren’t descriptive, much less finding the right command by guessing. It certainly improved, with GUIs being available for most stuff, but if you want something specific, is still feels pretty rough on the edges sometimes, from the eyes of a normal user.
If you mostly need your basic apps, like browser, some office apps or a music player it works great, though.
