Ask HN: Have you built a hybrid mobile app? What's your experience been like?

I recently read about how Basecamp uses an iOS&#x2F;Android &quot;shim&quot; and serves up Rails-rendered HTML&#x2F;CSS&#x2F;JS in their mobile apps:<p>https:&#x2F;&#x2F;m.signalvnoise.com&#x2F;basecamp-3-for-ios-hybrid-architecture&#x2F;<p>Have you used this approach? If so, what has your experience been like?
