Had my Note since Friday and it is a cracking phone. I've come over from iOS5 just for a change really. I'm still finding my feet again with Android. The screen is great, not retina, but still excellent. The actual size takes a bit of getting used to but that will come.
I would say Android is quirky. I have had a couple of newbie issues, but have asked about these in another thread. I would say the only thing that I find a little disappointing is when the screen dims, its not very fluid and that the white is not brilliant white.
The new Android 4.0 looks great, although the current one is new to me.
