The twisting system that was introduced on the X41T and was used until the X230T was an interesting solution but in my experience has issues as it aged becoming what I'd call "loose" or "floppy". If you were lucky enough to not experience that, I can certainly see it being desirable in several applications. The point about the style I completely understand. The thin pen is not quite as nice, especially for serious pen users. I often would see people carry a second full size pen. And yes, soldered RAM is essentially never ideal. In my mind, these products are so different.
