Mobile usability is one of

carry out a task. We will discuss mobile usability and related best practices in detail

It's Not All Rosy??”Mobile Devices have
Limitations
It becomes critical to understand mobile usability not just because users are in a
different context when they access mobile web, but also because mobile devices
have their own limitations. Mobiles are not full-fledged computers. On top of it, each
mobile device is different. Manufacturers have to distinguish their devices for them
to sell. Network operators sometimes offer customized phones, and they are tied
heavily into their way of things.
Typical mobile devices have screen sizes from 120x120 pixels up to 320x240. This
means you can show about 6 lines of 25 characters in a screen! They may have a
QWERTY keyboard or stylus, or have just the numeric keypad for input. They may
not have processors that can deal with complicated calculations or even the RAM
to hold your entire page before rendering it! They may support only a limited set
of image and multimedia formats??”e.
