Texas Hold'em update

You know, I'm really enjoying Texas Hold'em.

Here's the thing though, I've yet to play it on-line. I've stuck with single-player, and limit play at that ($3 & $6 bets). Haven't tried no-limit or pot-limit yet.

The game's interface is very simple, easy to follow, and a whole lotta fun. You can basically play the game with one hand, since all you need to do is press a few face buttons. All my matches have been played with me laying on the couch, my cat laying on my stomach sleeping, and I'm petting her with my left hand and playing with my right. Good relaxing game.

I have a couple questions though. First, if anybody has tried it on-line, how is it? Is it fun and tactical? Or does everyone go all-in on every hand? Also, what happens when your "bank" runs out? It appears that you start the game off with a certain amount of money in your bank, from which you pull funds (entrance fees, etc.) When you leave a table you take your winnings (or losses) with you and they get added back to your bank (or permanently deducted). If you completely run out of money, what happens? Don't tell me you have to buy more with Microsoft points!!!

If anybody knows, let me know.
