Let the hive mind of Engadget get that for you.
"I'm in the market for a new phone and money isn't a limitation. I'm also not partial to any particular US carrier, but here are some of the features I'd like to have: WiFi, GPS, good coverage in lots of places, push Gmail (a must!), physical keyboard (a must!), a touchscreen, decent battery life and a relatively slim body. And please, nothing that has a fruit logo on it. No offense to the fruit fans, though. Thanks!"
1. A long press of the Home button now acts as a task switcher - like Alt+Tab on Windows. It is possible that this was always there as a feature and I just missed it, but I doubt it because someone thought it necessary to develop a task switcher app, which I had installed and found very useful until now. The native Android one works better and I don't have to use the camera button like I did with that3rd party app.
2. This one is a definitely a new feature but less interesting. When you connect by USB to a computer, you now get a sound notification and a little usb icon also appears in the top left corner of the screen.
