I’ve been using KDE primarily since I started using PCBSD back in 2008 or so. I got used to KDE back then, gotta have my wobbly windows and desktop cube eye-candy, you know. Since the switch to TrueOS, one of the first things I do is install KDE through the appcafe, and go from there, usually without any problems. I know it “bloats” my system, but what’s the point of having capable hardware if you don’t use it? I also install the other DEs such as MATE, LXDE, Gnome, Enlightenment and Xfce just for demo purposes. I end up with lots of File Managers and browsers and system setting/control panels, but disk space is cheap so I don’t mind. I’ve always felt one of PCBSD/TrueOS’s strong points is its ability to have multiple DEs to choose from (instead of having to use a specific distribution to get the DE you want like in the Linux world), it’s about freedom of choice, right? This probably “pollutes” my systems somewhat, but I haven’t noticed any serious issues, generally speaking. Though one time I uninstalled googleearth, and it blew out the KDE install. Simply had to reinstall the KDE meta pkg, and I was back in business. Enlightenment locks up when i right-click and navigate the menus, but that same issue has been found in linux, so no big deal. In terms of attracting regular users to Open Source OSes, I think the main consideration for the average former Windows or Mac user is the DE. With TrueOS, you clearly have the most freedom of choice, and with things like Cairo-dock and highly configurable DEs, it’s easy to get a DE that you like, even something that looks and feels and works just like your favorite Windows or Mac version.
