Imagine a device similar in look to MacBook Air 11" with touch screen. That device would run both - Mac OS X and iOS (you choose which system to boot, and if you are already on OS X for example, you can press one button to switch to iOS in a matter of seconds) . Of course cellular, 3 usb ports, high battery life and retina display. If you choose to run OS X you can use touchpad/mouse + keyboard. If you choose to run iOS, you can also use the touchscreen. What do you think? Would you buy it? I definitely would! Apple should make a device like that! I don't want to carry 2 devices (Air + iPad). iPad is not a true computer, it is very limited, however very convenient. MB Air needs iOS/iPad functions and apps - creating such a device would be a perfect solution. I prefer to take one device which works like an iPad + Air.
