I'm search for computer and telephone?

Devices’ hardware and software characteristics have a big impact on what content is possible and meaningful to be delivered. Usually the web content is designed for desktop PCs, thus unpleasant and even rarely useful from a small-screened device. Nowadays mobile phones are rapidly becoming increasingly powerful (both from hardware and software point of view) however their screens will remain comparatively small. Often also the navigation is hard. Equipped with a small phone-style keyboard or a touch-screen (for the PDAs) the users might lose more time in searching where on the page the information they need is than in reading it. We can imagine alternative ways of navigation, for example voice commands. The memory available on a mobile device is also relatively small. It is possible to use extension packs on some devices like PDAs, which reduces some of the restrictions.
