Some Big News Today...

I'm very seriously considering this. Darn I still don't have a credit card...

I imagine there will be a statistical writeup on the sales after it's over. I'm really interested to see the details

There's more info about the average contribution on http://www.wolfire.com/humble now.

Quite interesting, taking the average contribution for each sale (per platform) results in roughly:
70.9% of sales - Windows (53% Contribution)
16.6% of sales - Mac (24% Contribution)
12.5% of sales - Linux (23% Contribution)

I'm probably out a few percent but that should be broadly correct.

Edit: Clearly I'm a total noob and missed the blog post about this: http://blog.wolfire.com/2010/05/Linux-users-contribute-twice-as-much-as-Windows-users

FTA:
"Our breakdown for number of donations per platform is: 65% Windows, 21% Mac, and 14% Linux. However, when we look at the amount donated per platform, we see something different. Our breakdown for total donation size per platform is 52% Windows, 25% Mac, and 23% Linux. "

Okay, I'm in. No offense to the foundations but I sent 100% to the developers. They probably need it more.

I did the same... and again with a gifted bundle. I think our world is plagued with too many starving artists.

I'd be curious to see the distribution between charity and developers.

Nearly one million dollars and still 7 hours left. Totally incredible! I don't think anybody expected so much money. 

Aquaria for Linux works flawless over here, btw.

Just made my own 'purchase', amazing how much money this has came up with.
