I've got one too--and a 4K TV. Like you said, it's not necessary but it's pretty nice. My worry is that next gen is eventually going to be here so the moniker of "most powerful console" won't really mean much. While it'll still be the most powerful eighth gen console, as time passes, the power difference becomes forgettable (if that makes any sense). The time is fast approaching.
The most powerful title is obviously fleeting. But we're potentially talking years of X1X being the best console for visual polish. That was certainly a motivator to getting a X1X. It may be another two years before we get more powerful consoles. Also, how much more powerful will they be than the X1X? If the aim is $399 that certainly limits potential. MS is treating the $399 X1X as a deal. But we'll have to wait and see.
I've had the X1 since launch and frankly its nice having the option of better graphics without having to jump to another platform. Also, I already have a library of games designed to take advantage of these specs. In retrospect, the X1X was kinda like next gen hardware without having to wait for good games. 2013 was a rough time, I played some underwhelming games just to see what my new hardware could do.
