This is sad.
There are very good reasons for this, I don't fault any customer at all for this, but nevertheless it's the case that over and over again I'm see people do the following:
Buy an expensive TV with high internal framerate and smart this-and-that.
Be turned off by the image artifacts from the interpolation
Be annoyed by a bug in the smartware
And end up turning off options left and right resulting in a 60Hz non-smart TV to be happy.
Beware the statistical correlations that sound like they're indicative of something. Drowning deaths are tightly correlated to ice cream consumption. In fact, be wary of any statistic that is stated as if it comes with a self-evident conclusion: there is no such thing.
