Well, what I see on the N900 is that it might be hard or outright impossible to do flicker-free rotation effect, which might be desirable -- the current effect in mcompositor looks quite good :). I do not know if the delay and spike in cpu as seen on the N900 while switching (under Maemo) is caused by the underlying fbdev, Xorg, or the combined cpu usage of all applications being notified of a geometry change. Actual rotation of the framebuffer data is done way faster by omapfb than with GLES.
