Components, no so bad? Please help.

From what I've read on the subject it's not simple about performance,

although that's a big part of it. It seems to be more about the fact
that design patterns exist the render components unnecessary in most
situation and it's about reducing complexity, by more refined coding
conventions.

I also understand that Rails 2.0 may eliminate components from the
standard libraries, so as a new Rails developer I will choose to avoid
them entirely and stick with the patterns being promoted by the Rails
core team.
