That's YOUR opinion and seeing how well both the SIII and Note have sold, its not a popular opinion
Agree.
The Note isn't for people who have a knee-jerk reaction to how huge it is. It's more for people who are elated to have a phone that big upon hearing about it.
The GS3 has a design that is quite disappointing to a lot of people out there. It seems that that phone was designed more by lawyers than by Samsung design. Did you see the video where the iPhone 5 beat it on a drop test? Not something people should consider buying.
The Galaxy Nexus 2, a collaboration between Google and Samsung, will likely yield a more conservative design that is functional and receives timely updates.
Disagree.
OP, I went from iP4 to the GS3 and contrary to Calidude's opinion, there are LOTS of people who love the design. Just because he is a strong advocate against it, doesn't mean his opinion reflects the masses. I once made a thread complaining about the design (it turns out, once I got a case that was super slim and barely added any bulk to the phone, I love it), and I got gently reamed by the S3 forum users. So there are plenty who really like it.
Personally, and this is just my opinion, the best step would be to go into the carrier's store, and get your hands on both devices. The size of the S3 constantly freaks out my 3GS toting buddy, he doesn't want a phone with a screen larger than 4.3". For me, the sweet spot WAS the Gnex. It was the first Android phone I went to look at when I first considered the switch. 4.8" is the BIGGEST I would ever want to go for something that I still use as a phone often.
All of that being said, from what you said you want to use it for, the Note2 does seem like the size you would be wanting. S3 can view docs etc, but you still have to stretch/zoom it around. And the websites that come up, are set for mobile web sites, which apparently the Note 2 has full webpage view.
The S3 has more than enough screen real estate do do most of whatever you want before hitting to the tablet kind of feeling. It is more portable and less conspicuous than the Note. I saw one in the wild the other day and went... damn! that bad boy is HUGE. This coming from a 4.8" screen user haha!
Best thing, go into the store, get some hands on.
