I agree. No IPod and no need to tip every win. If you want to tip, tip the dealers when they rotate out, and when you get up. Tip the barmaids for every drink, if you drink, but don't drink alot if you want to win.
But the main thing is Do everything the same, every time. Look at your cards the same way, stack your chips the same way, announce your bets the same way, put in your chips the same way.
Don't watch the turning of cards. Watch the players react to the cards, and then glance at the cards.
Identify the pigeons and the sharks, and play accordingly.
