A smartphone is probably best described as a hybrid of a cell phone and a personal computer. The ability to access the Internet from anywhere allows users to perform work outside of the bounds of a physical office and to remain perpetually in touch through social networks. While this ability gives users the potential to be more productive, it also carries some unique disadvantages as well.
Small Screen Size
Smartphone screens generally measure just a few inches wide and in length. Accessing websites and e-mail from small screens involves extensive scrolling to view all the information, and may be difficult for those with poor eyesight.
Awkward Keyboard Size
Alphanumeric keys are smaller and closer together on a smartphone than they are on a full-size keyboard, which can be problematic for those with larger hands. Some smart phones have QWERTY keyboards, which are meant to mimic traditional computer keyboards. Still, it is not possible to type on the keyboard as fast as you can type on a full-size keyboard consdering one hand is generally used to hold the smartphone.
Most cell phone providers require users to sign long-term contracts. Internet access is provided at an additional cost, raising the cost of owning a smartphone to £45 to £65 or more per month, depending on the terms of the contract.
Wireless Access Protocol (WAP) uses software to optimise websites for the smaller screen of a smartphone. Not all websites are WAP-enabled so some cannot be accessed, or if they can, they may not show all the content. Images may not appear and scrolling the entire web page can become tedious due to the small screen size.
The small size, lightweight factor and portability of smartphones allow them to be carried at all times, which makes it difficult for some people to designate a clear delineation between work life and home life. Frequent checking of e-mail and Internet applications takes time and attention away from interpersonal relationships.
