More PHP

UPDATE: I added a poll.

I'm doing some VB.Net at work today. (Whew!!!) But last night at home I did some more PHP. I am getting tired of Notepad very quickly.

So, I pose 2 questions to PHPers... What do you use to develop/write PHP in?
Why is it so great? What's it got in it worth coding with?

Tell me in the poll to the right.

On a personal note, my wife and I got back from the Berkshires last night. Already looking to go away again, one weekend does not restore you completely, but then again, what will in this system.
