If you feel that the bamboo works for you, keep using it.
I'm really confused as to why this needed a new thread.
With the Cintiq, you are looking at your hand and what you are drawing/painting. For most other tablets, you have that third stage of disconnect.
You mentioned in your other thread that you're oing commercial work, right? If its good enough for what you're doing, no need to change.
BTW, did ya have a link to your stuff?
