I don't see the point in opening pages in new windows. They clutter everything and to switch between them you'd usually reach down to the taskbar and click on the window you want. Tabbed browsing essentially operates similarly to the Windows taskbar except that your pages are all contained in a unified interface so that there's less clutter and micromanagement. An operating system's taskbar should honestly only be used for switching between the programs themselves, not individual gadgets or windows within that program. One of the big reasons I'm not using GIMP, for example, is because, when I accidentally click outside one of the windows and bring another to the foreground, I need to bring back all five of the little windows GIMP has (why do they have individual taskbar entries, anyway?!). That's just a waste of time in my opinion, though, hey, it'll be fixed in 2.6 with its new Single Window interface. Really, having a single window is the way to go.
