Not very much different from Galaxy Tab 2 10.1...but the few differences that i can see between them are :
1.Galaxy Note 10.1 Camera is 5 Megapixel, with auto focus and LED Flash.
2.Galaxy Note 10.1 came with stylus (pen for writing or painting or whatsoever on the tab screen)
So that's it....I can't find any other differences (I mean in terms of its interior spec),
processor speed same (1.4GHZ Quad Core), same android version and so on.....

Thank You :)
