I have one. Its nice but its not being totally trouble free.
It keeps dropping its connection. It just wont stay connected and updated. On occasion the liveview stops responding to input, or freezes for 20 seconds or so. Sometimes you think its going ok but then it kicks you out of what you were viewing and tries to reconnect, but fails.
Its hard to know whether its the liveview, the liveview app or the Desire that's the problem. Ill try it with my Dell Streak for a day or 2 to see if that's better.
