Got mine last night about 3 am pacific, although maybe it came earlier, but that was the time I just happened to wake up.
A few things that I have noticed:
1. live wallpapers, yeah it looks cool.
2. I like the improved photo gallery, makes things look cleaner also does support pinch to zoom.
3. Browser also supports pinch to zoom, although I fould that to be a little shakey and not so smooth.
4. Google weather/headlines app added plus a widget for it. Actually I like this and have been messing with this all morning with the headlines. Takes up a row of realestate on the screen, so it would have been nice to add additional home screens.
5. Something goofy happened after install, the four buttons on the bottom of the screen lost their light as so did the pull out keyboard would not light. I went in and toggled the display setting between auto and a set brightness level a few times and then turned on the light in the room and it started to work. Don't know what that was about but it is working.
6. One thing I thought that used to work but I honestly can't remember, is when you hit the search function and turned the phone sideways, I thought it went into landscape mode. For some reason it is not but maybe I don't remember that correctly, but I swear that mine did do this.
7. Also the live wall paper is working on the unlock screen before you unlock, which I think is pretty cool.
8. I tried the text to speech in text messaging and it worked like a charm. I can see me using it to do a quick text if I can't be looking at the screen to type.
9. Pinch to zoom does work in Google Maps now.
10. Also right after the download happend I checked my downloaded apps and the one for Visual Voice Mail was needing an update. I updated it but didn't really notice anything different. I hate when you get an update and it doesn't really tell you what they did.
Other than that, I haven't tried the rest of my apps and don't really see anything else to be excited over. Oh except that it seems the battery life looks to be a little better.
