It keeps coming back to

It keeps coming back to this again and again (and matthew will sooner or later have to fess up that he was wrong). People love tabbed browsing. As reported on the front page of mozillaZine.org, Timothy Dyck of EWeek says after 32 days of using Mozilla exclusively:

First, there are two things Mozilla does better than IE, and both are compelling enough to me to make the switch: tabbed browsing and pop-up-window blocking.

Tabs are beautiful, beautiful things. I often have 30 or more browser windows open for days as I research several stories in parallel. Now I have four or five Mozilla windows open, each devoted to one particular topic, and each with several tabs open. This really suits the way I work. This was an Opera invention, but they're well done in Mozilla.

While he gets it wrong about Opera inventing tabbed browsing it does serve to articulate that yet another case where tabbed browsing offers something that the window manager doesn't. Multiple windows with multiple tabs (Timothy's and my usage) can be extremely helpful in organizing catagories of pages. Matthew would have me rely on my window manager but doing so would cost me this valuable organization of pages. There's simply no way to accomplish the same goal of having multiple catagories of pages grouped together while maintaining a full and usable history across all of the pages.
