Huh, Enterprise usage of Blackberry was very very high and then it was not. And at one point SOA, SOAP/WSDL/XML usage was very very high and now I am told in my very enterprise job I'd be fired if I dared bring those names up.

Usage being high doesn't say anything about quality or suitability of a product specially in enterprise settings.

Honestly, it does. Enterprise software does need high reliability.
