The faux chrome grille is holding up really well. I picked mine up at the MS Store the first week of October, and its been in and out of my bag, on multiple work trips since. It looks as good as the day I purchased it.
Performance is good since the AU update, I've bounced back and forth between Preview and Stable releases mainly due to bugs in the fast ring builds (last weeks fast ring build has a wifi issue that makes it hard to stay connected and wont work for me between dropping wireless and miracast connectivity). I'm back on the latest stable though and all is well.
Camera is also improved significantly from the shipping firmware, things are getting better with each release. There was another firmware update last evening that fixed some bugs, waiting to see an official release notes though.
Last piece I'll comment on for now is continuum. I have the desk dock as well but have been on the road so much I picked up the lap dock which I've been living off of. It works well, gets decent battery life, and is far more responsive than I expected. I use it fairly often with wireless connectivity to the lap dock and while there is a performance hit over wired, it's much better and more responsive than I expected. Overall build of the phone however feels premium for sure.
