When Motorola announced the Atrix smartphone at CES this year, the tech world sat up and took notice. What's this? A phone that acts like a computer? Sure, the Google Nexus S has a built-in near-field communication chip that will (eventually) let you buy a sandwich on your way to work just by tapping your phone on a till . Yes, the LG Optimus 2X has not one but two processor cores, providing a refreshingly fast browsing experience and true 1080p HD video playback. And if you believe the rumours about the upcoming iPhone 5 , it will sport a higher-resolution camera, a near-field communication chip, and an end-to-end screen. What we haven't seen is a smartphone with a built-in desktop operating system, until now.
