Switcher here, too. I did an even trade (felt like I got the better end of the deal) with someone, my 4s for his gs3. It only took me a few days with the gs3 to fall in love, so I upgraded to a Note 2.
I have been an iPhone user since the original, so it was a tough decision for me. It's been about a month now, and while I am REALLY enjoying my new phone and have no desire to transition back, there are some things I miss. But the good stuff from the Note 2 outweigh the stuff I miss from iOS, and I still have an iPad.
