if you design these things, then this might be pertinent.
i suspect i'll prefer the old (FOF2) interface to the new one (FOF2K1), for a few reasons:
the lack of evident "hot keys" for getting around.
where do i click? with the standard windows-like interface, buttons are clear, and i can't miss them. with puresim, i find myself "searching" for options more often than i should. this happens with FOF2 as well - who knew clicking on the standings would do anything?
i prefer having the ability to re-size/minimize my windows. alt-tabbing out of directX-type programs sometimes screws things up.
FWIW...
