Nice! Steel Storm was a nice add earlier, I'm probably looking forward to play it more than the original five games (although all are interesting). But getting the bundle #2 games too, that's pretty cool.
Already bought it earlier for a bit more than the Linux average. I think I directed a bit over dollar to Child's Play and a bit over dollar as a tip to Wolfire, who put the bundles together, but don't have a game from themselves in this time around, so that's the only way they're getting any money (back) from this.
Re: charity, I read the Wikipedia page earlier, and the bundles are about selling indie games, the charity thing is more of a nice opportunity to raise some money to them as well. It's definitely cool that you can give most or all the money to them though. I think the bundles together have raised hundreds of thousands of dollars already for the charities.
