iPod touch: FaceTime- Video calling is in full effect on iPod touch. Now your friends can see what you’re up to, when you’re up to it. With the tap of a button, you can wave "hi" while standing in a foreign country, get a second opinion on a pair of boots, or have your friends bear witness to the everyday pranks, bets, and dares they otherwise might have missed — new iPod touch to new iPod touch or iPhone 4 over Wi-Fi. And come face to face with even more fun.
Retina display-Thanks to the Retina display, everything you see and do on iPod touch looks amazing. That’s because the Retina display’s pixel density is so high your eye is unable to distinguish individual pixels. Which means images in games, movies, and photos pop off the screen. Text in books, web pages, and email is crisp at any size. And everything is sharper. No wonder it’s called “cutting edge.” - and more new features!
