I agree... for me the temptation for buying 
animation art is in NO way diminished by CG. 
Darn those genga and douga! ;) I happen to think 
they're tremendously cool on their own, too... 
even for shows that are cel animated I've seen 
several sketches for scene layouts that have pan 
notes, all kinds of directorial comments... 
droolworthy stuff in my book. ;) (Almost makes 
me wish I'd splurged a LITTLE more at the Taro 
sale!) And one of the best pieces in my 
collection is a set of genga and douga of Lina 
from Slayers.... a STUNNING image of her that 
I'd have never been able to afford in cel form. 

It does, however, mean that I watched my crappy 
first-sub-release copy of Hunter x Hunter Greed 
Island's first ep very carefully indeed to see 
if it was CG or not. ;) (Well... that and I'm 
completely freaking obsessed with Hunter x 
Hunter and was squealing in fangirl joy the 
whole time. ;))
