As the experts say, you can’t get Ruby on Rails at the first run. Got the book Agile Web Development with Rails by Dave Thompson, read it, all examples worked perfectly, but everything looks like magic. There is plenty under the hood when it comes to ROR and you are totally abstracted while you build your web application(s). I still have to understand the 80% of what I read.

There almost no need to write Javascript, no worry about cross browser compatibility. Ajax works perfect, you can make your application work fine in Javascript disabled web browsers. As with any technology, the success of the platform is measured by what could be launched from it. We are planning for a ROR application, when time is right we will launch it and see if it makes an impact.
