I agree with higher IP ratings - the higher the better. And impact ratings too, I like my phones to be tough! (that's why I buy Nokias).
I'm not bothered about bezel-less displays though, I have to put my fingers somewhere!
There is no IP69 certification. There's an IP69K certification, but I don't think any normal Nokia user needs to worry about dropping their phone into a jet steam cleaning factory.
Not normally no, but what a marketing opportunity!
