That's a lot of empty space. Also, how about just:

return screens.empty() ? gfx::Rect : ...

+  if (screens.empty()) {
+    return gfx::Rect();
+  }
+
+  return screens.front()->GetAllocation();
+}
+
+// static
+gfx::Rect Screen::GetMonitorWorkAreaNearestWindow(gfx::NativeView view) {
+  // TODO(beng): use |view|.

Remove beng here.
