Amazing, open-source alternative to traditional desktops. It's simple, clean, and beautiful. Definitely makes me more productive. In the end, I have very few complains about it. If you are a Linux user, I can almost garuntee you have already tried it. If you are not a Linux user, this is one of the best ways to jump into that world.
I decided to switch to Linux early this year, trying many distros and desktop environments. Elementary was the only distribution that felt like it "just worked" and didn't need tweaks and themes to make the desktop satisfying to use. It also ran much faster than GNOME based distros like Ubuntu on my aging laptop.
In my opinion it is the most well-designed and accessible flavor of Linux right now. Perfect for old hardware and for friends who want to use something simpler and lighter than Windows.
