From the press release:<p><i>The ASUS Padfone is a device that explores one possible convergence between two popular mobile devices - the smartphone and tablet. The Padfone solves the problem of data transfer hassles and multiple SIM cards when both a smartphone and 3G tablet are used. With the Padfone, the smartphone docks inside the tablet to give users an expanded view to suit their tasks. With the phone docked, it can recharge from the tablet's larger battery and the tablet can also make use of the smartphone's 3G internet connection. The dual interfaces for both the pad and phone ensure an enhanced user experience as the layout is automatically adjusted for all activities such as video conferencing, web browsing and emailing.</i>
