Advantages and disadvantages of touch screen

 

Disadvantages of touch screen

• screen has to be really big not to miss things when pressing them with your finger: I only like HTC Touch HD, screen size wise, and big screen means increased size of the device
• big screen leads to low battery life
• touchscreen means screen can’t be read too well in direct sunlight as it applies an additional not 100% transparent
• touchscreen devices usually has no additional keys (see the iPhone) and this means when an app crashes, without crashing the OS, you can’t get to the main menu as the whole screen becomes unresponsive
• touchscreens usually have low precision, virtual QWERTY keyboards being one of the most annoying things
• most user interfaces are not optimized for thumb operation, so a stylus in necessary, and this means using two hands
• screens get very dirty
• these devices require massive computing power which leads to slow devices and low battery life

Advantages of touch screen devices

• big screen is ideal for web browsing, picture and movies
• touchscreen gadgets usually have simple user interfaces, which are more intuitive (iPhone once again is a good example)
• touchscreen devices have fewer buttons that might break after a few months/years of operation
