That's not Unity, that's GNOME with extensions mimicking Unity.
Also instead of changing desktop environments, he could install the clean/stock GNOME session and then add Dash to Panel + Arc Menu, which would give it a Windows-like taskbar.
If you want a better taskbar/dock, try different DE and see how you like it.
