It looks like Mac OS's dock, which is IMHO the best way to present a taskbar. Good to see this in Linux distros as well, such as Elementary OS (which looks a bit ugly, but is getting there).

Minimalism is about getting out of people's way. Many extras are never used by most people and shouldn't be visible, or they are annoying. If you want those extras there should be options to enable them or make them visible. Maybe even specialized software. But don't force every obscure feature onto my desktop!
