I have the original Note and really like it. I've gotten spoiled by the size of the screen, it's great for my purposes (a lot of ebook reading, taking notes with Evernote). I can't justify an upgrade for a while yet, but I'll be very interested to see what they do with the Note II.
Prior to this I had a Galaxy S2, which I loved. I considered it the perfect phone (a water spill killed it ). The S3 looks amazing as well.
Nice that the screen is no longer pentile. It's a huge shame they didn't put the Exynos 5 in there, though. This is basically just a Note 1 with a slightly larger screen IMHO (the quad core 4412 isn't that big of a deal over the old one).
