MBP + External Monitor Question

Let's say you've got Spaces set up to have 4 different spaces. That gives you 4 desktops to work with. If you then connect an external monitor, you've got an extended desktop that spans two monitors. When you use Spaces, you still get 4 different spaces, but now each consists of a monitor pair. (The monitors appear side-by-side in my configuration, so I get 8 screens, one pair in each of the 4 Spaces regions.)

 

I just got a MBP 15" and have a Dell 2407 and it works just as the previous poster reported.

I just made the switch from PC and can tell you it works really well. I have played with dual head setups on windows boxes and that just what it is.... playing, maybe it's better now.

With osX you just move the monitors into arrangement of your liking under system pref and move the menu bar to the monitor of your choice and you are done, no drama at all.
