It's a little hard to take you seriously when you seem to dedicate the first 4 paragraphs to dunking on Microsoft. Windows is no more of a Mac clone than MacOS is a Xerox PARC clone. Word is just a rich text editor, same as Excel is database software and Bing is a search engine. Call it whatever you like, but people all-too-soon forget that the root of all software development is "I wonder if I could do this better?"
