For instance say I am looking for a bit of text.
In *nix I have vi in which I can type "esc/foo." Now, before I can blink the I am at the first match. Hitting "/" goes to the next one just as fast. If I don't know what file to look at, grep will tell me quickly.
Visual Studio has a search function, but it's not regular expressions by default, will not work on all of the design surfaces, and requires going through several dialogue windows. Typically I have to put my hand on the mouse to get any results.
For some tasks platforms and tools can make a big speed difference.
However it is true people are complex and hard to predict.
Perhaps some c/c++/QT programmers when given a, a shiny new windows based development environment, may enjoy the extra time they spend searching through source code. Who knows?
Except c/c++/Qt programmers -- they're pretty simple to predict, apparently.
The best devs I know tend to accept challenges to learn new systems and do well whatever they're working with, even if there's a particular language/platform they love more than others.
