Web is becoming the new graphic library, based on the success of xPUD project, we make it further by adding following components: 1) WebKit-based browser with finger scrolling and dobule-tap zooming function, 2) A BPMF-friendly virtual keyboard integrated with SCIM input method and 3) Touch-enhanced user interface based on xPUD’s plate framework. By using simple software stack, we’re pretty confident that xPad could be an alternative of MeeGo or Android as a lightweight and easily customizable tablet OS.
