Not OP, but for me the answer to your question is: is a tool I need. I _could_ use Windows, and absolutely not Linux/BSD (for the programs/tools I need for work), and, frankly, I don't think Windows is better.
Yes, I know that's not completely true. I _could_ use Linux (I even used Solaris on a notebook for 2 years in the past and I survived) but the cost in terms of effort, lost productivity would be higher than I'm ready to pay. It's a rational choice.
