You can still have 40 separate applications working on Windows 8 across 3 monitors. Windows 8 didn't take away anything (that's a big misconception). Just go to the desktop and use it as if it was 7. Same programs, same windows (lowercase w) and same behavior. You never have to use a full screen app -- you can even delete them if you want.
The new full screen stuff is there if you have a tablet, but if you don't, you aren't forced to use it.
I'm here in Redmond visiting Microsoft this week. As you might image, they are all using Windows 8. And I've passed hundreds of cubicles of workers and they're all using the desktop, just like you said: lots of windows floating around.
I don't know why everyone keeps thinking Windows 8 has removed that ability. That's like saying Windows 7 took away the command prompt and "forced" you to use the desktop. The command prompt is not only still there, but many IT professionals use PowerShell daily for their tasks. In the same way, Windows 8 has a new interface, but many people still use the desktop for their daily tasks.
