Introduction

Abstract

Thanks to continuing advances in mobile computing technology, it has become possible to perform complex data processing on-board small handheld devices. It has taken over a decade from moving to handheld devices that can place and make calls, send short message, organize the calendar and save some data, to handheld devices that are as powerful as our ten year old computer servers. It has never been a better time to exploit the increasing computational power of small handheld devices like smartphones and tablet computers. The market studies have shown that tablet computers will soon replace our laptop computers. In a recent market study in the USA, it has been found that 46% of Americans think that tablets will replace laptops.
