When it comes to full-size Windows smartphones, the Motorola Q has few competitors. This may be about to change: an image of what's purported to be the HTC Excalibur has leaked to the Internet. In addition, a few key specifications accompany the rumor. The Excalibur would be a quad-band GSM phone with WiFi and a unique interface twist. Instead of a jog dial (as seen on Blackberries and other smartphones), there's a touch strip to the right of the screen that should make for less wear on people's thumbs as they scroll through menus and media. No tentative release date has been given other than "soon."
