Good show, pretty good setlist with a few nice surprises - Right Where You Belong and The Way Out is Through were unexpected. I was happy to see finally see the Fragile-era guitar come out again (he used it on Final Solution, as well, I believe).
Other specific comments -
Trent was pretty chatty, he had two fairly long speeches. One saying how much he loved Chicago, playing here back in the ooold days (1989), how much he loved the scene. And he also reassured us that it wasn't truly the end, that he, and the band, together and individually, would still be making music, though he didn't have give any specific details.
March of the Pigs, I have never seen him pause so long in the second chorus, the crowd was just howling, it was great.
Trent had some fun in Piggy, messing with Ilan's drums. He was pushing them around a bit in the drum breakdown, completely knocking over a drum and a cymbal or two... the stagehands had a fair bit of work to do after he was finished
Ruiner is always great and I'm glad 3killa got the one song he was hoping for.
The barricade arrangement was novel to me (I wasn't there last night). Instead of going straight across as usual, there was a lane in the center going a good 15-20 into the crowd. It really cut down the lateral motion; there weren't any big sideways pushes that threaten to sweep you off your feet, at least not up front near the rail. But I definitely felt the weight of the crowd, it was more crushed than Webster.
Peter Murphy... man, what a vamp. He didn't fuck up the lyrics too much this time, just came in a bit early and had to repeat a line. The two covers they did were pretty good, even though I hadn't heard either before. The first was a bit of a quieter one, with mainly just Robin on guitar; cool to see Trent joining in with a recorder part! And Final Solution was suitably powerful (Pere Ubu, even though he slagged on Cleveland earlier

).
And ending on Hurt, it's the right way to do it imho. I'm quite happy for that to be my last NIN live song... until, as Trent says, he starts doing whatever else they'll be up to next.
