I first ran into the Note when it was only in South Korea. Everybody who owned one was significantly active: a construction site manager, an architect with a kid (who used it extensively for site sketches), a mother of 2, a couple college kids, a salesman with extensive travel requirements...not to mention that the best way of getting around in Seoul is pretty much on foot and public transport.
I will say that most of them also carried around a pre-charged second battery since finding charge points can be a problem when out and about in a big city (without holing up at a coffee shop (if you can find a plug) for an hour).
They all loved it, and one of their friends with an S3 was planning on "upgrading" to it. It was a little big for small pockets, but was perfectly fine holding and using it if you can get over the requirement of only using one hand to operate a phone (I haven't used one hand ever, even with my old flipphones back in the day).
It did look a little funky being used as a phone, but when lots of people have one it tends to look more normal.
