You see them everywhere now at coffee shops , in the park . Everywhere there are people holding what sort of look like giant cell phones and tapping away on them with a serene look of joy on their faces . They're tablet computers – or tablets for short . But while we see them more and more everyday , you often hear people who don't have one ask a very simple question ; what are they ? Tablets are hand-held computers that are either flat or wedge-shaped , and function by having the user touch the screen to initiate whatever action they wish to perform . They have no physical keyboard and are completely portable , using rechargeable batteries for power . They can use wireless and/or mobile technology ( 3G ) to connect to the internet . They are smaller than most laptops , and are capable of running a wide range of applications , from video games to email clients .
