I've had a Note 3 for 8 years, it's still fine but l needed more storage.
I bought the 10 because it's a year old but new, the reviews say its solid and it's a third of the cost of the latest Note 20!
There are so many differences with the Note 10, it's a better shape to hold, there are more stylus functions and Google's latest android is great.
I'm very happy!
