I guess it's the 'large' part that turns me off. If it's actually far away so that you need to scroll a lot to get there, it just feels like it's more work to me. Sort of replicating one of the less appealing features of a physical desk, the mess that it quickly becomes if you manipulate a lot of documents. I don't even use workspaces that much for the same reason, and having tabs takes away a lot of the need I feel. You even retain some sense of physical distance because of the tab positions.

To stay with the physical analogy, the layout I've described is like always keeping all your documents in two neat stacks before you. Except that it's much easier and quicker to flip pages to the top than it would be with physical documents, so you're rarely tempted to start spreading them out.
