She's a big beast, but you fairly quickly get used to it and going back to an iPhone seems tiny. The screen is gorgeous, it's lightning fast, and overall I'm very impressed. I was worried about subpar music performance, but I got poweramp and double twist to sync music from my mac to the phone and it works great and sounds great with my klipsch x10s. The widgets are great (as a new android convert) and I think I'll be keeping it for the next 12 months until I get a look at the iPhone 5. I had an iPhone for 3 years, and still have a 4, but have grown pretty bored of rows and rows of icons.
I thought about the nexus, but there's no microSD slot and 16gb isn't enough for me. And anyway, the note will get the ICS update in a few months time. As for the s-pen, I don't think I'll use it a huge amount, but it's pretty nifty for taking and editing screenshots.
All in all, very happy. I'll be even happier when I can get the native email app to push!!
