You don't watch much Japanese Animation do you.
 It is only the USA that can't draw and needs to
 go computer generated 3D. I suspect that software
 rather than hardware is the factor here as it seems
 all TOP 3D animation uses custom in house software.
 A lot of traditional ink and cel style animation
 is done on computer but it does not have the
 "special effects look" that 3D has,so most people
 don't notice it. 
I watch a lot of Japanese Anime, and trust me, there is a lot of computer
generated work in there.  While I've not seen much computer generated 3D
animation, there is definitly a lot of 2D that is computer generated.
On the 3D note, I was rather disappointed when I got the "Lensman" movie on
Laserdisc a few months ago.  I'd seen it back in '93, and had forgotten that
it had a bunch of 3D animation mixed in with the traditional 2D.  Simply
put, 3D animation, doesn't always age that well!
