I really like this monitor, but fear Viewsonic's reliability. In 2008-2009, my work group bought a few hundred value-priced 27-inch Viewsonic monitors and 23-inch Viewsonic TVs. The failure rate was unbelievably high, easily surpassing 50% in the first year for the 27-inch model. The 23-inch TVs fared better, but surpassed 50% failure within 3 years. Viewsonic replaced the ones that failed under warranty with refurbs, and they failed, too.
I personally bought one of the same 27-inch models from Costco for home use after using one at work, it failed in less than 3 months. Thank goodness for Costco's warranty.
Maybe just really bad quality control on a couple of low-end models, but it scares me when the author writes "The obvious question has to be: what’s missing?", because in my past experience, what was missing was quality control.
