In addition to everything else mentioned above, I think it was awesome how he drew a rectangular box in the middle of the screen and selected which app to open in there (calculator). That was sick!!!!! S-pen functionality definitely improved!!! If I get N3, this time I'm probably going to find uses for s-pen
Need to see when my wife is due for upgrade so I can give her my Note 2
Regarding Gear, a bit disappointed. I like the design and functionality, but 24hr battery life (which is questionable and more like 18-20hr), that fragile looking camera on the wrist, proprietary charging cradle, no mentioning of waterproof, only compatible with Note 3 for now (wait for S3/S4/N2 upgrades next months for compatibility - does that mean Note 2 getting 4.3?!?), and probably a hefty price tag kinds of puts it down.
Btw, I almost fell off my chair when the guy raised his hand to his ear to demonstrate answering the phone "HOT smartwatch" style. Those HOT guys on kickstarter were using that gesture as their main selling point, and I bet you Samsung has it patented already.
