I've been coding PHP for years and am just starting to learn Ruby on Rails. I'm not a programming expert at all, and so most of the objections mentioned would take me a while to parse.

From my perspective, Ruby on Rails is really, really difficult so far. You have to learn to use the terminal (which I've seen other people in my position use to totally mess up their computers); to make a simple application you're already looking at maybe a dozen files, many of which you don't understand; most importantly for me, because there is a lot of stuff going on that you can't see, it's very hard to extrapolate from examples.

I have learned what programming I know from breaking apart example programs and then using the pieces to build other things. I'm not good at learning from textbooks or tutorials. This has proved very difficult with RoR so far. I'll take components that look like they should make something happen, and then they'll throw an error that I don't understand and can't seem to locate.
