What exactly do the web professionals use?
I noticed some questions about use of hardware devices and choice of operating systems.
In an example of a classroom survey, a customer said that, 50 out of 52 students used Mac in Canada.
And an friend of mine did not get further responses from a possible German employer when he replied using Ubuntu and Windows to customize Magento projects.
Well, what exactly do the professionals use as their core tools for web development?
What hardware, IDE and OS choice makes you a professional web developer?
And where should the current were developers jump to cope this technology and preference trend?
