The Cons of a Touchscreen Display
The three most dreadful complaints would be maintainability of the touchscreen, low precision, and lack of user interface in the event of a freeze. The first being that other accessories should be bought in order to preserve the touchscreen display from normal wear and tear and accidents, which can be expensive, such as the OtterBox products for the iPhone that can cost up to $50. Secondly, it is also costly to repair or replace in the event of an accident, even with warranty the device usually has to be replaced completely, such as the iPhone and iPod devices, or cost a lot to repair, such as the Barnes & Noble's Nook.
Low precision is one of the curses to having a touchscreen display and through the many advantages and disadvantages of touchscreen displays, this one is key when deciding if it is worth it. Low precision means accurately typing, selecting, pointing, etc. on the display. For example, on a cold evening, the display may not pick up on the finger or may end up picking other icons around the finger. It makes it difficult for those who cannot use a pen or other such device for typing.
Lastly, losing user interface is not only annoying, but can pose a serious problem when accepting and declining phone calls. Sometimes, in the event of a display freeze, having additional buttons help in restarting or exiting certain programs, but most touchscreen displays only come with a few buttons. Other disadvantages include hand fatigue from holding the device in one position for too long and cannot be used with just one hand like other devices with keypads attached.
What this means is that if you like to take care of your phones, this would be perfect, but in the event that you aren't a very good caretaker for a touchscreen device, then sadly this type of display would not be ideal for you.
