Much of the true benefit would be things like catch-up TV, and other streaming video (films and such), natively on the device. Otherwise it's like going back a few years, when many TVs didn't have freeview tuners, then new ones came with them built-in.
For some, DLNA capabilities are quite a plus.
As to the apps - well they're always going to be a little bit fiddly or inferior to using them on another platform more suited. I often find, with things like iPlayer or ITV player that programmes that won't show up in a search on a device (smart TV or networked device connected with the apps on), show up when I access iPlayer / ITV player via the normal website on a computer browser.
Not sure I can get behind them, yet, as some kind of convergence thing, though - browser, games - surely people interested in those things will choose better options. Making them more ameniable to be used for media purposes (so catch-up, streaming, youtube, DLNA) all makes sense. But like smart watches, some of it doesn't make sense - trying to foist convergence on something for a poorer experience, seems flawed, really.
