===System similarity===

It can be very convenient to have a phone system which is very similar to the computer system people generally use.  Apple Inc. has gone a long way in this direction, making their iMac, iPhone, iPod, iPad, and all other devices use very similar systems.  This enables the user to learn just one basic layout in order to use any Apple device.  Windows took steps in this direction as well, with their [[Windows 8]] [[operating system]].  This was designed to work on both desktops and touchscreen mobile devices such as smartphones.  There are two main problems with this strategy, only one of which is external.

#Similar systems are only convenient for most when the systems are practical and easy-to-use of all devices.  Apple has done a pretty good job of doing this, but Microsoft was not so successful.  In the end, Windows 8 did not sell very well, and they had to rush to fix a few of their mistakes (with [[Windows 8.1]]).

#Similar systems tend to have similar vulnerabilities.  While an infected Blackberry smartphone would probably be unable to infect a Windows computer (unless the malware were designed to use use Blackberry as a vector to attack Windows), an infected Windows Mobile system would have an easier time of infecting a Windows computer when they are connected.  Apple devices have the same issue, if not more so, since their systems are so similar and interconnected.  If an infected application is installed on an iPhone, it can then spread to an iMac next time it is connected.  Then if an iPod or smart watch is connected to the laptop as well, they can become infected.  Some unfortunate people have lost their identities in this manner, because in a single stroke, the person's entire digital life can be taken.
