Nice to have company, at least. :-)

I agree, eliminating the conditional with polymorphism would be hugely
preferable, but it feels a bit wrong putting view stuff in the
business logic. The other day I happened across[1] a project called
Draper (https://github.com/jcasimir/draper) that implements
Decorators/View-models for Rails apps, which looks interesting, and
might be the sort of thing to fill this gap. Haven't had a chance to
try it out yet, though.

Cheers,
Simon
