Love it. Keyboard takes a little to get used to. Much easier to use the virtual keyboard on this than my ipod touch. Very quick and easy to use. Still getting used to some settings but there are tons of shortcuts in the market for it(Such as turning on and off wifi, blue tooth, music, brightness, etc)
The screen smudges easily, but I'm getting an invisible shield put on tomorrow. The phone has a nice sturdy weight to it. Audio is very clear on it, both speakerphone, music and earpiece.I'll post more about it after using it more.
The turn by turn nav is pretty awesome. It comes up with streetview when you arrive. The voice is just something to be desired.
