That was probably one of the most anti-climatic events I've seen in awhile. They pretty much leaked everything months in advance, which took all the wind out of the sails. Nonetheless, this is still a great phone, but there isn't really anything all that spectacular about it.
As for iOS6, I'm skeptical. After playing with it the last couple of months, there's several things that irk me, but none as much as Apple Maps, it's a regression in some areas. The lack of transit directions is a downgrade. Addresses are pretty much hit or miss, as well. Typing in some addresses gave me "no results found" (even if I was within a few hundred feet of it), while other times it'd jump me into Florida or Massachusetts. Worse, if you click a map direction on a website it no longer brings up the map app -- you're just given a Google map in the browser without directions or your current location. This is where Android's Intents system outshines iOS. I pretty much had to resort to using Google Maps in the browser or taking out my Nexus 7 when navigating around Chicago the other week. As is, Apple Maps seems like a potentially huge fail, especially if you live in a major city. Hopefully it gets a lot of love within the next month, or they allow Google to actually release their own app. I think the map feature they thought they were able to produce, when that decision was made, was probably very different from the one they were actually able to produce.
