Klondike is just a fancy name for that Solitaire card game we all know and love, so nothing new there, and iQuiz is a remixed version of the older iPod "guess which song this is" game. Vortex, meanwhile, is a circular, three-dimensional brick-busting game in the style of arcade classics Breakout and Arkanoid. All three titles were developed in-house by Apple, and both Vortex and iQuiz can also currently be purchased on the iTunes store.
Even if the new nano is the Gimli to the old nano's Legolas, it's nice to see both it and the classic getting more into games. Jobs also promises more iPod games coming to the iTunes Store (Hey! You know what would be awesome on the iPod? Peggle!)
Although not addressed during the event, it's assumed that the brand new iPod touch will join the iPhone in being unable to play any games purchased from the iTunes Music Store.
