DISADVANTAGESHaving 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.

Fingerprints of the user obscure the screen if not handled carefully.

Though the touch screen technology contains some limitations but it’s very user friendly, fast, accurate, easy for the novices & fun to operate. It has been widely accepted. And now by just modifying a little it can replace the mouse and key board completely in near future
