John Gruber points out the difference between iOS and Android: World of Goo HD for iPad [iTunes, $4.99] sold 125,000 copies in its first month on the App Store. This makes it the "fastest selling version of the game," beating Steam and Nintendo Wii sales figures for something that's been out for two years on other platforms. And as Glenn points out, it's coming to iPhone and iPod Touch.
Amazing.
