Pre multitask facility with Palm

Palm's WebOS delivers two important improvements that the iPhone can't yet match: true multitasking between applications, and a subtle notifications system that doesn't interrupt your train of thought. It does that while unveiling its own stamp on the multitouch user interface that Apple introduced to the masses with the iPhone and finding room for a slide-out hardware keyboard favored by CrackBerry addicts.

WebOS applications will be created with standard Web development tools such as CSS, JavaScript, and HTML that run on a version of the Webkit engine. This doesn't mean they are "Web applications," which require a connection to the Internet to work. It does, however, mean they are (in general) more lightweight and less-resource intensive than iPhone applications, which are developed using the Objective-C programming language

That may limit the performance of WebOS applications. Don't expect the sophisticated gaming community, for example, to embrace the Pre. But Palm's approach means it will be very easy for anyone who has developed a Web application to get up and running on Pre development, which could help expand the number of applications in the early days of the device if the smartphone world likes what they see.

Other mobile operating systems--notably Android and Windows Mobile--allow multitasking, but Palm has developed an elegant way of switching between "cards," something vaguely akin to a combination of Windows' Alt-Tab switching and Mac OS' Expose, or switching between tabs on a Web browser. New applications can be launched using the "Launcher" software button on the bottom of the home screen, and users navigate between different applications by flicking finger left or right Google
