I use a text editor, a shell, other tools. The idea that I want to fight is that linux is a far better environment or mac is far better than windows. I mean, just use what you want, but when you say "x" is better is just because (usually) you are mixing personal like/dislike with ideology (and in the IT community there is a lot of ideology: just think about apple...). I don't care about Microsoft, and all these talks about "the tools" are all right until a certain point. Some times, I've to be honest, seems like talking with kids. I mean really you need ubuntu to do a good job? Maybe developing rails is a far better experience on linux for some reasons I don't know (I'n not a rails develoepr): so you'll use linux. People use linux as a server because is a unix-like platform costing no money. It's better than microsoft server. Good for them and for me because I also use linux. I use windows because I'm used to this platform, I need some tools are just on Windows and I don't like too much the Apple OS. But I've to be honest, I don't like also Steve Jobs and the ideology that Apple brings with its cult. So I'm religious as you. The important thing is to be aware of why you think in a certain way and why you take certain decisions. Tools are tools are tools.
