very difficult question.

OS4 running Timberwolf and Abiword under X11 on Pegasos is not very slow so we can think this applications will run at a confortable speed on X1000 regardless to X11 weight and non hardware acceleration.

So, my point on view is X1000 "will be" better for wordprocessing (Abiword and maybe OpenOffice 4 kids) and maybe for internet, but MorphOS have a big chance to be better on 3D gaming, and video playback.
We have to remembre the fact Morphos have a very good internet browser and we dont need something like Timberwolf.

The only thing missing at this time on morphos is an Office suite with a real wordprocessor managing all file formats.

The sad X11 solution on AmigaOS4 is better than nothing on MorphOS.

I regret the lost of Papyrus.
