All of those companies (Commodore, Atari, TI, RadioShack) may have made some questionable decisions but in the end, consolidation was bound to happen. Incompatible software and even disk formats fractured the market too much. It was fun at the time though :-)

Willow still has some textures for sale at Daz3D. The product page only says Willow but Google says Willow DaNaan, so I assume it's her.

I still have Poser 2. The figures were disappointing though, of course they were still meant mainly as models for those who could actually draw.  Missed 3, got 4 and somehow found PFO. Don't remember too much about the clashes. I remember Thralldom,  Lannie's, Greylight,  Ghastley, HappyWorldLand... Mostly gone though Greylight  and Ghastley still live on.
