I played on the electronic poker tables in a SNG in florida, ehhh it was ok, i like the feel of real cards etc much better.
For roulette though this is awesome, unless i am mistaken they are probably getting rapid roulette. The beatuy of this is that it still uses a real roulette table, but each player has his own screen to place bets on. No need to have to dodge other peoples arms to place bets and allows up to something like 24 players on 1 real.
here is a link for more info on this if you want it:
Nice article on it and some pics at bottom:
