Well, my wife go me one before I got my driver license, and I find it useful, for opening bank accounts, credit card account, etc.. Immigration is happy to have copies of it when I do the yearly extensions.
Nothing "great", but quite useful. It probably depends on where you are. My guess is that in places like Bangkok, Pattaya, etc. the Farang gets processed somewhat differently. I am out in the sticks, beyond the black stump.
