Not a jerk, just tellin it like it is.
I came over to the Note 3 from a HTC One with Kit Kat (I also run Kit Kat on my Nexus7). Most of you will be let down, there is no second coming with Kit Kat.
This "update obsession" that some seem to have is more interesting to follow than the updates themselves.
My HTC One was the perfect phone until the update. Screwed up my blue tooth call quality to the point that I could not use any of my hands free kits (2 Jawbones, Plantronics visor kit, Jabra Freeway). I actually had the phone replaced...worked great until I updated to Kit Kat then the same problems. I live in a state where you must use hands free while driving....I drive a lot.
The call quality on the other end was so bad I was asked many times to call back after I reach my destination.
I will repeat blackwe387's comment, Be Careful What You Wish For....You May Get It.
