Based on Chen's quote, we'll stop making hardware if our hardware isn't making money, I'd say yes this is a last-ditch effort. BlackBerry doesn't have any options left so they tried to build the ultimate enterprise smartphone. For the reasons Michael lays out here, an "Enterprise Phone" is not enough anymore. Sure, there are still some white-collar pros who just want a work phone and are ok with carrying two phones, and may like the Passport. But that demographic is shrinking and BlackBerry won't be able to make enough money from them. Hail Mary is a fitting description.
