So I have a MBA with Lion. I am used to working with Windows 7, where all apps almost can be considered "full screen apps" if they are maximized. So, I only see one app at a time, because it fills the screen. To switch between them, I move the mouse to the taskbar and choose which one to go to or use alt-tab. It appears that Mac users historically are more used to work with smaller windows distributed throughout the desktop space, so they can see several/all of their open apps simultaneously but at the cost of cluttering the desktop. Therefore multiple desktop spaces is a step forward i guess, by providing more space/less cluttering in the individual desktop. Or what...? I just don't get the point. I maximize all apps I'm working with in Lion and then use mission control to switch between them, just as I did using the task bar in windows. Why is several desktops with a maximized app window in each better? Am I just being a very window'ish Mac user? Also it appears that you can't even have different files/folders present in specific desktop spaces only (e.g. a "work" desktop space with all you work related folders present on this desktop only)? I think I just prefer one desktop, keeping all open apps as large as possible, so the active one covers the desktop entirely and the switch by mission control... Unless you guys explain the points I'm missing....?
