I\'m new to Ruby on Rails and so far, I\'m having a lot of fun learning it. Coming from the .NET world, it\'s been quite a switch as my IDE (Visual Studio 2008) sort of hand
Try Netbeans Ruby Edition. It's not quite as nice as RubyMine but it has built-in svn support and similar templates to TextMate. I like it, but then again, I also haven't released the project I'm developing yet so I can't speak much to productivity.
