I haven't used the note. And I don't know if the OP is talking about screen appearance or just the idea of bigger screen. But I'll address the latter.
While I love(d) the iPhone. Now that I use a Skyrocket as my primary phone, I honestly struggle when I go back to use an app or do something on the iPhone. It's not because the OS is boring, It's not because it's "dated" or any silly comment. It's the simple fact that when you get used to using a larger screen - a smaller screen just is harder to read. Is the screen as high PPI as the iPhone. That matters. Definitely matters. But on my Skyrocket (4.6" I believe) the screen is great. I have no complaints. And the fact that I can actually read text, app labels, and have all that extra real estate is important. And valuable.
Remember when people joked that the iPad was just a larger iPhone/touch? Not that the Skyrocket is THAT big. But the response is the same. Screen real estate is everything.
I have the skyrocket as well. I just got through working on a client's iphone. Maybe I'm getting older but my skyrocket is just so much easier to read. I don't give a rat's *** about ppi or whatever you call it.
