You know what I'd like, Sir Pugglesworth? A detailed review of your impressions of the console. Don't be shy, now! Controller, graphics, interface, features, etc.
I don't have a lot to say exactly. But I'll answer everything you mentioned.
I think user interface is okay. Kinda confusing at first finding your downloads, where my library is, etc. Sometimes I try to open the store or start a game and it just sits there doing nothing. I've had to close the game currently running to fix that. Watching video clips seems to load a lot, I don't think its my internet connection causing that. So some weird stuff but it works okay for the most part.
The controller is great. It feels comfortable in my hands, I like how the buttons feel, and that touch pad thing is neat. However, the L2 and R2 buttons still feel weird as triggers.
I'm playing some of the best graphical showcases on PS4 at the moment; Driveclub, Infamous: Second Son, and The Order: 1886. The attention to detail Sony puts in their games is impressive, but its not a far cry from stuff we see on X1.
