15.  DISADVANTAGE
 Having a big bright screen and needing massive
computing power to run this means a very low
battery life
 In direct sunlight it is much less efficient and
most of the time very difficult to read the screen
 If a touchscreen device are to crash the whole
screen would be unresponsive, and because of the
lack of buttons recovering it would be very
difficult
 They usually cost more than other devices
