Companies like Google or Microsoft have a hard time getting users to upgrade to the latest version of their operating systems. On Android for instance, a quarter is using Android version 4.4, the most recent version of the system.

It is not necessarily the fault of users that their systems are not upgraded as manufacturers may not provide updates to devices which leaves users standing in the rain and without official options to update their devices.

It can sometimes be a necessity to compare different versions of a file. Maybe you want to make sure that a file you burned to disc or stored in a backup is identical to the original, list all changes that someone else made to a file, or compare files after a hacking attack to find out if they have been modified in any way by the hacker.

File comparison tools are one option to do so. These programs provide you with the means to compare one or multiple files quickly which is one advantage that they have over comparing data manually.

Having to do less on a mobile phone to get to the desired result is something that many users appreciate. That's probably one of the reasons why companies such as Google or Microsoft are adding direct information to their search engines in form of Knowledge Graphs and other items displayed in the results.

The main reason why I like it is that I dislike having to type a lot on the smartphone or use it to navigate web pages.

Most developers have preferences when it comes to Developer Tools. Some swear on the ones built-in Chrome, others prefer Firefox's or add-ons such as Firebug.

The problem here is that these tools are limited to a single browser. If you have to switch to another, for instance to test how services and sites look in that browser natively, then you switch to that browser and use the tools provided by that browser or in that environment for the time being.
