Yeap, tried both LXDE and Gnome today (only for 1/2 hour each
) on a 512 MB memory virtual machine. LXDE had a much better performance on such a poor hardware comparing to Gnome (as expected).
Although I prefer KDE4 over Gnome2.32, it is nice to see Pardus running different desktop environments for different tastes. Besides it is stable & supported!
