I had Nexus 10 for some time which is the highest resolution display in the market right now but returned it as there were some hardware issues, battery doesn't last long, and couple of crashes a day. I recently bought Note 10.1 at Costco for $429 which is a really good price.
Resolution is low (specially if you have used iPad or Nexus 10) and it is bothersome if you "really" pay attention to the resolution. Once you are browsing a website or reading a book, you only pay attention to the content not the screen so at that point resolution doesn't matter. There are so much functionality built into this tablet which you'll use in real world that it outweighs any other high res display tablet. Just to give you few.. Not including the obvious S-pen advantage
1. No crashes compared to at least 1 or 2 a day on Nexus 10.
2. Battery is a powerhouse. I can easily go 2 days with moderate use one one charge. I had to plug in N10 every day and battery drain was just too steep.
3. No heating after playing graphic intensive games like Asphalt 7.
4. Side by side apps. Truly multi window/multi tasking tablet. You can crop a picture from a website and drag it to s-note (pretty cool).
5. Pop up apps like calculator, calendar etc.. which pops up without leaving your main app.
6. Change display brightness without leaving your app. Notification bar pops from bottom right which has brightness slider. I use it a lot based on the app I'm using.
7. Split keyboard for fast typing.
8. Hand writing recognition is really good, you can write an email using s-pen.
9. Even though screen resolution is low, videos look pretty good.
10. Using s-pen to hover over the menus to open sub-menus is awesome. S-pen works like a mouse.
11. It tracks your eye so if you are looking at the screen then the display doesn't go dim on you. Perfect when reading long news articles.
12. It saves your clipboard history so you can access any previous clipboard item from a special key on the keyboard.
Its been only few days I have had my Note 10.1 and I'm still learning about the functionality built into this tablet. It would be awesome if they release Note with high res display but without it its not bad either.
