No harm in trying. I will always talk them down whenever the opportunity arises.
OTOH, the brand new ASM, card-reader shoe combination, which I first saw at Parx in PA, seems to be a great way to speed up play once the operators get used to them. There is no handling of chips (except for quitting payout), no opportunity for chip cheaters, no arguments about who got dealt what, since an ongoing record is kept by the machine, no waiting to count the value of your hand (there's a readout that updates your total with each card dealt), no mistakes about you buy-in amount (the computer keeps track of each and every buy-in amount). As long as they don't use it to analyze whether you are counting or not, I think this approach works for everyone. If they are allowed to use such a machine to analyze your play, I wonder how difficult it will be to defeat it. Anyway, that is the only downside I see, and it remains to be seen whether the law will allow it and whether the casinos go that way.
PS--There always seems to be a downside to whatever improvements are made.
