As a computer science, I use tools that suit me in ways that I find that makes doing my job more faster and effective. If there is a faster, more streamline and easier method of doing the same task with a different tool, I will immediately adopt it to my toolbox.
This semester I really discovered the power of using the Cygwin to compile my C programs on windows. It comes with a terminal that functions just like a UNIX terminal, but in a windows operating environment.
One of my favorite tools to use is Sublime Text, which coincidentally is a text editor that I used over Emacs because I thought the latter was extremely clunky and awkward to use.
Currently tools, are starting to become more similar to each other as newer versions start become available. What I could see happening is that eventually there is going to be a point where there could be lawsuits occurring when companies will start suing other companies on basis on infringement. This could also spur more innovations to make tools more effective, such as haptic feedback or alternate means of input.
