Totally agreed with this. That's not to say I'm not looking forward to the PS4 - I am tremendously, but I really like what I'm seeing from the X1 right now and it feels like a big step forward in terms of usability and functionality overall.
A UI shouldn't be a "feature", the less intrusive the better, snappy, accurate, reliable, that's all you need.
I've just bought a laptop, my first experience of Windows 8.0 (now 8.1), looks nice, but the tiles & apps, are nothing more than an inconvenience, getting in the way of accessing the desktop as quickly as I would like.
Speech recognition, that's the definition of a gimmick, most of us have it on our phones these days, I doubt many have actually used the feature, after the initial novelty value.
It's also worth pointing out UI's, and all that's associated with them, evolve over time, it's not a set in stone feature set.
