I have mentioned most of my experiences in that thread but to recap briefly.
I have been using the phone since Tuesday on VF. Experiences so far are generally good but there are some issues. Note I have never really used an iPhone so can't comment on the differences.
3G coverage is generally fine (the phone notes the connection is HSPDA).
Turn by Turn Navigation doesn't work as noted - you can speak the destination, it finds it and then says there is no route. Google maps works and does use the GPS to show your exact location and based on my limited testing, the point does move as you drive. I am looking at purchasing Copilotlive rather than deal with rooted phones etc. but it's unclear from their site and from their tech support and twitter responses whether or not I need to purchase the software with US maps first and add ANZ ones or is there is a package that includes the software and ANZ maps.
No multitouch in the base apps but I downloaded the Dolphin browser from the App store and it supports multitouch.
No BT voice dialling - that's annoying since it means I cannot legally make a call when driving. Perhaps that is a good thing.
The on screen keyboard takes time to get used to but perhaps that is an Android thing. Getting the position right is hard in portrait mode, easier in landscape. And the predictive typing is reasonably good.
Voice recognition is quite good. It's cool to be able to speak something into the search bar and after a bit, have it bring up a Google search result. Also works in any field where you can type stuff.
Be careful with realtime synchronisation if you don't have a data plan! As I noted in another post, since I had setup my Google account with the phone, it was trying to synchronise Google Calendar, GMail (OK) and also Picasa albums (not good!).
Exchange integration is okay but not as good as the iPhone (which I have setup for people). You can synchronise Mail and Contacts but not the calendar for some reason. In the interim I have done what I did with my SE P1i which is to use Google Calendar Sync on the desktop to my Google calendar and then use the realtime sync on the N1 to sync the appointments to the phone. Because of data plans issues (I have only a 100MB plan) I don't do live Exchange Sync but grab mail when I need to.
The phone occasionally bring up Voice Search and other apps when you haven't apparently done anything - just moving the phone around. Not sure why - perhaps the screen is overly sensitive in places.
Tons of functions I am sure but it comes with no manual. I had to download the 320 page manual and print it out - some weekend reading :-)
Would be interested in other people's experiences when they get their phones.
