So I have had the Galaxy S 3 now since it was released, and I have had a chance to mess with it and get used to it. Here are my thoughts.

I enjoy looking at the display and the large display helps out for remote sessions and when I am at work doing server administration and whatnot. As well as being nice to read email on and whatnot.

The phone is very smooth and everything runs great on it.

However,

Touchwiz had to go. I put the nightlies of CM10 on it and it runs great with those. only issue for me at least being that USB audio is still not supported for some reason on the current builds.

As far as device things That i do not like. Even though I enjoy looking at the screen I find that the screen is a bit too large to be able to use the phone with one hand and this causes a bit of a headache sometimes.

Also i find that compared to my Droid 3 it does not get nearly as good signal at my house.
Other than that the phone is fantastic and i use it all day every day,

Generally I unplug it at 7am and do not plug it back in until around 11pm and it still has 60% or so battery life remaining.
