I am coming from the Moment/Intercept. I know my standards are pretty low after suffering through those 2 POS phones, but I have been amazed by my EVO3D.
The call quality has been on par with pretty much any other cell phone I have ever owned.
This thing is ridiculous fast. I know my old phones were lacking in the processor area but, good god, things just happen instantly on this thing.
The lack of speaker phone volume does scare me a little about over sleeping in the morning (but truthfully I am scared I am going to over sleep every morning)
The 3D has been better than I expected. I think I need to learn how to frame shots better for better effect. I consider this more user error than phone error.
I have been using mostly 3G (4G in my area is isolated to small pockets I don't frequent), but the browser is stupid fast. I think a some of this is a benefit of dual core awesome sauce, but after I click on the wrong link the the page is loaded before I have a chance to hit the back button. I know this is a little thing, but damn this thing is fast.
I did make a trip to the part of Indy with 4G. Wow! I could get used to WiFi speeds all the time.
The battery (no 4G) kicks ass. The first couple of days where pretty hard on the battery, but I was customizing, downloading of apps, and general tweaks (plus I just couldn't put it down). After I got settled into my normal routine it easily outperforms both my Intercept an Moment.
I really haven't spent an extended amount of time using 4G. I really can't comment on the effect on battery after extended use.
Overall I am surprised at how much I enjoy Sense. It is the little things that make it cool. The phone rings louder when it is in my pocket!
The lock screen is frigging awesome.
I find myself pushing the power button just to see the weather lock screen animation.
HBOGO on a 4.3 inch screen = awesome!
