in reply to Productivity with <i>any</i> tool?
In my opinion this is impossible.
To be productive and efficient with a tool, you need to know not only what it does and how it works, but also a lot of details of it's usage. Though it's the everlasting illusion of the GURU who comes and can handle anything within a hand stroke just using the perfect tool for it. But for example looking to job offers assumes that a lot of personal managers share this illusion while requesting knowledge of nearly everything related to computers with experience of at least 5 years witch each one.
But we all tend to specialize in certain directions. And if somebody forces you to use an uncomfy tool while you know a better one to solve the task, well resign the job or argue for the better tool, but don't share the illusion they have and better help them to wake up.
Have a nice day
All decision is left to your taste
