I never understood this type of workflow and when I was in school it was everywhere, it's like apple was pushing for people to have little windows strewn out over an otherwise gorgeous display.
Also, it's nice for spacial awareness. I feel a little bit lost when a window takes over the entire screen and blanks everything else out.
It's even better in ubuntu because desktop switching isn't just left/right, it's up down. So I can really think geographically. I guess that's just the kind of brain I have - for example, if I want to look for tickets for a movie I want to see, I search "movie theater" in google maps and click the theater in the location I want to go to, then navigate through ticket buying etc. shrug who knows man
Uh... because with three 30" monitors, it would be like sitting in the front row at an iMAX theater?
