I have had one for 1.5 monthes & love it. It's not as large as the 5.5" screen would have you believe and the extra real estate makes for great web browsing and reading. I would recommend it.
I was a diehard iPhone lover. I was so skeptical that I kept my iPhone4 and added a line for the Note. I literally couldn't imagine like after the iPhone. 2hrs with the Galaxy and I was already convinced. The big screen is awesome and it has a reject list where you can block/unblock numbers from your phone without having to contact your service provider. The OS was the deciding factor; 1000x better than the iPhone.
I have it too, Brittany! I don't like the lag and can't remember the app for saving energy. My battery is always dead and I don't browse or talk on the phone too much. My Angry Birds addiction is another story. jkjkjk!!!
