I have never mentioned web development *requires *Windows anywhere in the article. If you read correctly, here is what I said
“However, some advanced commercial software like the Adobe suite (Dreamweaver,Photoshop etc.) is not available on Linux, due to which, thousands of web developers and designers choose Windows over Linux.” I am merely pointing out that many web developers (mainly people building websites and not “web-based” applications) *prefer *windows as they like to use fancy tools like Dreamweaver, Photoshop, Corel etc. Personally I do everything on linux, and as you rightly said – development is far better on the linux platform. Where I work full-time, all developers use linux/Free-BSD to make web-based applications. Only the people who work on the designing part (User Interface) use Windows.
