While you're most likely right, it's just not transparent enough for my tastes. I've done enough programming in my life to know very well that I could build a poker-playing game that was tipped ever so slightly in favor of the house, and do it in such a way as to make it very unlikely that the player would notice. You don't have to cheat all the time to slide in under the radar - just cheat once in a while, enough to give the house edge a boost of a point or two.
Besides, those things are just waaayyyy too hyperkinetic for me. It just moves a little faster than I'm comfortable with, which is precisely the idea behind making them that fast - keep people moving, so they don't have time to think, and they'll keep feeding the machine until their bladders burst. It's an interesting study in human psychology, watching the video poker players ;)
