Heck, I'm surprised they haven't equipped the tables with RFID readers and use cards with RFID in them so a computer at the table can maintain the count and watch the bets and point out potential card counters.
Some Casinos Do. L'Auberge du Lac in Lake Charles does. I was there 2 years ago playing BlackJack so when I asked to be rated for my level of play, she went to the computer attached to the table and pulled up my stats. She was able to tell my average bit, how many hands I played an hour, etc. That being said, I know that computer must also signal card counting betting patterns. [Note to anyone that plays there: The 'button' the dealer hits before dealing out the cards tells the computer a round has started to collect the wager -> player position for the round.
There is a bright side. Companies start offering 'Unlimited Everything' plans (see Sprint) which force other carriers to do that. Then the carriers get into a price war over the unlimited plans and ultimately, the consumer witll win.
