I too just came back from T-Mobile store where I had an extensive opportunity to play with the Note 2 and here are some impressions from someone who is (was) very close to pulling the trigger on a Razr HD Maxx. I was positively surprised at the size of the Note. My biggest fear was that I would find it too big. I'm a guy of average height with no more than medium sized hands and had no problems holding it although I have to mention that I tend to use both hands when typing or surfing on a phone. The size of the phone did not make it feel weird using when it to make calls either. I usually keep my phone in my shirt pocket and it easily fit there without looking too big at all. I also tried it in a front pocket of my pants and it didn't feel any more noticeable there than my current Droid. I'm very surprised to say that for me size is now a non issue for me.
The screen absolutely blew me away. I cannot recall ever seeing a screen on any phone that was as impressive to look at from the standpoint of clarity, brightness and colors. I like the screen on the Razr HD Maxx but with one reservation, that being that when looking at text with a white background, even at maximum brightness, the white is not true white - it is even less bright white than on an older Droid. That is not the case on the Note 2. The screen is fantastic. I also tried typing on it and found the larger screen definitely made it easier to type and improved the accuracy of my typing. Web pages I viewed on the Note were much more pleasant to view. I also found the stylus easy to use and definitely useful although it might take the rest of my life to learn how to use all of the functions of this phone.
I'm very happy with Moto and have had a series of Droids all of which had great radios and zero problems. I was definitely planning to buy the Razr HD Maxx until seeing the Note 2. For me it now boils down to whether or not the Note will have an unlocked GSM radio like the Razrs do. I often travel abroad and need the ability to pull out the Verizon sim when out of the country and pop in a local sim card. If I can do that on the Note 2 I'm definitely buying it. If I can't I'll be buying the Razr.
One final observation. I have found the Motos to be very solidly built and every one I have had has survived a few accidental drops with no problem whatsoever. As a result I have never paid for insurance on one and will not if I end up buying the Razr HD Maxx. After seeing the Note 2, I would not buy that one without insurance. It does not seems as solid and that huge glass screen scares me into protecting it with insurance if I buy one.
