The "pure Google" thing is getting funny. What could possibly be better about having less features rather than more? Back in the days of 512K of RAM when SoCs were slow and overlays crude, poor performance drove people to AOSP/AOKP and de-bloated custom ROMs. That's not really the case anymore. The h/w is now more capable than the UI and apps running on it.
I played with a friend’s N10 over the holidays and, feature wise, it was a barren wasteland compared to the Note. The phone UI on a 10" tablet is bizarre. Similarly he was amazed at what the Note could do that his N10 couldn't. The N10 has a faster SoC than the Note but when you factor in the PPI it's pushing and that memory bandwidth is hard-partitioned to support the display it's certainly not any faster. And with app incompatibility because of the resolution some apps behave poorly or don’t work at all.
The Note has IO accessories available to match the N10's ports, takes up to a 64GB exFAT SD card for expansion, has an IR port, larger speakers than the N10, and gets significantly better battery life and charges 1/3 faster. It also doesn't have light bleed.
Without question the N10 will get updates ten times faster than the Note. But so what, it'll still do 1/3 of the things the Note can do right now. It'll just be Google's barren OS with updates. I've disabled Google Now because I don't use any of their native apps that it depends on to harvest data and for some reason it thinks I work at a McDonalds because I stop at one frequently. As a value-priced consumption device with a great display the N10's a solid choice. For people interested in creating and managing content the Note's a better choice. Its 147PPI display is fine for pics and videos and doesn't require upscaling like the N10's display does. It's obviously not as good for text and computer generated content like the UI and that's a compromise you have to make to get the additional features. So for people looking for something beyond consumption I wouldn't be so quick to dismiss the Note. It's already sold 5MM units and I'd be surprised based on its limited distribution if the N10's sold 1MM.
OP, if the things in this video mean anything to you consider the Note. If all you care about is consumption and the display the N10's a better choice.
