79 to be more precise, it looks like windows 8. With the taskbar but not containing the open windows (I believe its hidden by default unless you come near it).
To see the open windows you click on the activities thing. This opens another full screen window
In the left you see what in windows would be considered part of the taskbar, containing your applications that you would be able to quickly launch and what you have currently open. (As gnome can't put things on the taskbar this is where you put stuff instead)
In the middle you see once again every program you have open on this virtual desktop (Why they then also appear on the taskbar thing is a riddle for me.). On the right you see a list of all your virtual desktops + 1 empty which can be used to increase the amount of virtual desktops you use.
Typing here does what you might expect, it searches for you applications and shows them a bit like windows 8 does. However instead of tiles you have icons and the list scrolls up and down. Clicking on applications shows you all the applications in the same list structure.
Did I already mention that by default GNOME won't show icons on your desktop? Like putting things in your desktop folder won't make them show up there.
Oh, and all gnome applications make use of client side decorations. Making you unable to change how they look. In fact, even when using a gui that doesn't render title bars Gnome applications still have title bars.
Oh, and 3 buttons on a title bar are too many as the default only have an X. If you want to minimize a program you either have to memorize the keyboard shortcut or right click on the title-bar and select minimize. (Thank god you can change that though, else the title-bars would be even more worthless then normal title-bars. Which is a miracle in and of itself >_>)
TL
R: I hate title-bars, gnome 3 is a piece of crap and you should use mate instead. Unless you like the tiles of windows 8 and don't mind to switch to another window just so you can see your task-bar >_<
