Rails is the main driver behind Ruby's success, true. And it really is a nice framework. However, Rails doesn't come rolled with a standard Ruby installation either, and 'gem install rails' is no easier or harder than 'cpan -i Catalyst::Devel'. Interestingly, I notice many of the new Rails 3.0 features -- most notably composable set algebra and increased modularity -- are features which drew me to Catalyst+DBIx::Class. I haven't worked with Rails 3 in detail yet, but I have some Rails work coming up in the next few months and I am excited to compare and contrast.
