BlackBerry announced on Friday that it will not be upgrading BlackBerry PlayBook tablets to BlackBerry 10 operating system, the company's newest mobile OS. BlackBerry 10 has won accolades from users and many reviewers, and in January, the company had committed to bringing it to its not-very successful tablets.

The news came Friday from BlackBerry's quarterly conference call with analysts. The company reported a loss of US$84 million on revenue of $3.1 billion, with sales of 6.8 million devices.

It's not known how many of those devices were BlackBerry 10 devices—the company's legacy devices remain popular with the CrackBerry crowd—but it was The Verge that noted that CEO Thorsten Heins said the company would not be bringing BB10 to PlayBook.

No specific reason was offered, but Mr. Heins did say that his engineers hadn't been able to get satisfactory performance out of BB10 on the tablet devices. Perhaps this shouldn't be surprising consider Mr. Heins's belief that tablets are naught but a passing fad that will be gone in five years (stated all the way back in April of 2013).

Which serves as a convenient reason to run this image again:

When your company's leadership is of that mind-set, what incentive would you, as an engineer, have to make it work? That's a rhetorical question, but if you're a BlackBerry engineer, please enlighten us. We would love your perspective. Feel free to write me at bryan2 at this site's domain.

In any event, no BB10 on PlayBook, leaving dozens of PlayBook owners feeling betrayed.
