Very good point about Samsung's marketing mindset. As we get ever closer to the convergence of personal technology into what theoretically will be a single unified and integrated system -- television, tablet, personal computer, phone, wrist watch and automobile chauffer, all rolled into one -- every device necessarily must be measured against every other device in terms of usability -- especially its user interface.
Samsung's SmartHub falls down badly on that score.
It's subjective, I know, but my "gold standard" is the GUI that Windows and Apple have made nearly universal. The SmartHub contains bits and pieces of it, but overall it's a radical departure, clumsy and unreliable, from the de facto standard.
And it's just too early for it to be on the market. Samsung still has not been able to log me into its own servers via SmartHub. It doesn't yet have a grasp of its own technology.
I've come to see all SmartTVs as a metaphor for a set of roller skates that are suddenly all the rage, a trendy new thing that can get me from my home to the grocery store, but with a lot of falls and wobbles and stumbles along the way. Meanwhile, there's a nice little Chevy (my PC) in the garage. It's a far superior vehicle. Why not use it instead of the roller skates?
