Right now, "gadgets" are extremely popular in China. Maybe because in previous generations they've only been available to the privileged elite.
For now I can only provide an anecdotal evident that most of the Chinese I know (including me) don't like 3D (TV or Movie). 3D movies are very tiring and draining to watch, and afterwards I don't remember the scenes as vividly as I would from a 2D screen.
I'd say this is just a sign for Xiaomi to show interest of entering the "home TV, phone, tablet as unified" system market. There are much to be desired there.
