I did do some ESD research/design once for a web tablet. Although the IC 
used (forget which one) was said to be ESD safe, firing at the touch 
screen with a Human Body Model ESD tester resulted in error. I then 
added R/C combinations to resolve this problem.

But I'm definitely not an EMI expert and would even think that adding 
resistors may make the problem worse ...
Are there any special considerations to take into account with (apart 
from PCB design and use of separate ground/power planes) ?

P.s: let me state that I was _not_ the original designer of that web 
tablet :o)
