ViewSonic president Jeff Volpe:

ViewSonic has made the strategic decision to focus our future tablet initiatives in emerging markets and niche verticals, where we can best leverage our core competencies to fulfill technology needs in regions and markets presently underserved by the widely saturated supply of mainstream consumer tablets. As such, we will continue to explore business-to-business opportunities in which we can leverage our technology leadership and longstanding partnerships to provide vertical market customers with valuable solutions not found in the existing mass market tablets targeted to consumers.

Translation:

We made a bunch of consumer tablets and nobody bought them.
