Yahoo finance kind of application

Hello All:

We are looking for various web development choices out there and many
have suggested RoR to be a good way to go with, especially its ease to
use and faster development.

The end result of the web app will look something similar to Yahoo
finance - so I am wondering if existing RoR views capability will be
able to deliver this to me.

My friends who are in .NET are Java tells me that its extremely easy
to do the views part, but my web application will be primarily driven
by growing data (web 2.0) - the model/controller part of RoR is
satisfying so far, but the views/UI is what making me think deeply.

Can someone give me some inputs regarding this. Thanks.

Best
