I was thinking about the new vibration trackpad in macbook pro (and others). The simulated click effect is nice because you can click even the top of the trackpad and it feels like a click. It would be pretty cool if they added this feature to iphones and ipad. For a more immersive effect when you click the ipad buttons you get a click feel when you push them. This would be awesome for the virtual ipad keyboard. They managed to fit the entire device in an air so its not to huge of a device really. It would be worth it even if it made the ipad air a hairline thicker just to have that button click feedback on the keyboard. If apple did this they would be the only tablet manufacturer that had haptic feedback. I dont know. Maybe im crazy. Just thought it would be cool on the ipad and iphone.
