i say independant desktops are better (if it can be done.. may take a little longer to redraw) this is mainly so that i can have my arrangments different to look better on the two orientations (some arrangements might have icons go to a different screen, hence will need two seperate portrait/landscape dekstops)

also with things like OMweather, i have it the width of my entire desktop, i would like to change the settings of this widget or use another widget on portrait.
