For all but the most insanely high-traffic apps, the best Ruby on Rails hosting solution these days is a combination of Amazon Web Services, Heroku, and a shared host like DreamHost.
This is because you should serve all your static assets from CloudFront and use SES for outgoing email. Your application layer should sit on Heroku (until it becomes crazy expensive), and your inbound email server, domain redirects, and miscellaneous stuff should be on a shared host.
TIP: use the promo code RHPROMO to get $30.00 USD off at signup with DreamHost.
