Another large concern about these phones is that they contain typically large amounts of private and work-related data that if the phone is lost or stolen, then it is a liability for hacking and identity fraud. If smartphones break, then it is costly because so much information is stored on them and the phones themselves are expensive. This is very easy to do because most of these phones are very fragile and have glass screens, so precautions must be taken to protect them. With all the applications and entertainment options, it would be really easy for users to get distracted at work. When comparing smartphones to office computers, smartphones have very limited memory storage space and they are not efficient to use for typing long reports on the small keyboards. The resolution of photos from a smartphone cannot replace that of a regular camera and most of these phones do not come equipped with a flash for taking pictures at night. Also, older people might not understand the new technology and the small screens can be difficult to use for email and other advanced functions for people with bad eyesight.
