I was so intrigued by your query that I popped into local John Lewis to have Win8 demonstrated.
Yes, you can get to a "normal" desktop with multiple windows visible and running but via a lengthy navigation for every program launched by starting from the tiled Start screen, pulling up some bar from the bottom to be able to click om "All Apps" and then be presented a sectionalised menu of all the programs (here called "Apps") indexed.
What I found missing missing here is that you cannot have a hierarchical (foldered) structure to this menu, where you would see a list of only the programs under a certain heading, like Games. All you do see is a list all the programs, well a whole screenful, divided by the section headings, and you have to cast your eye over all of them to find the section, say Accessories, and then the program, say Notepad, that you want.
I notice on the MS Windows web pages and videos it shows none of this, but just peeps pointing at the tiles on the Start screen.
