Anybody here like to draw on computer programs?

Not much.
They lack the subtlety and directness of physical media. 
A simple pencil and paper does the job much better.
Same for charcoal, conté, crayon, ink...no exceptions.

 

  Nope, not at all. 

  I used to try my hand at several different varieties and/or brands of them, none ever lived up to the promises on the packaging and in the sales pitches, not a single one. Especially disappointing were the supposed architecturally-related ones. 

 You?

I used to; a lot even; 

 

but i stopped not because i'm not interested anymore; but rather for personal reasons; because i have a criminal file with the police i feel like my creativity is less 'free' because of the police file. 

its hard to explain but if i didnt have that, i could more dedicate myself throught arts. 

 

well i enjoyed it a lot. because all you can do on a computer with a mouse ; you can do much more than physical drawing
