Having a Note 10 plus and still using right now. It has been a fantastic phone. It has never given a bit of greef. My wife's has been the same way. With that said it is getting a bit slow at times. Other than that I would buy it again.

I am in the same situation and I was about to pre-order the new note but honestly the difference is not big enough for me to pay out another 1300+ dollars and yes if you trade on your note 10+ they will give you 650.00 off the new note20 models and 150 but (only of you pre-order the phone) the s pen does not have enough significant upgrades they have the upgraded camera's, refresh rate has increased, upgraded screen and of course upgraded software the s pen not many updates either they increased writing speed and im sure added gestures but stilll not worth it and I buy there phones every year but im honestly thinking about skipping this year but I will say this if u can honestly say the few upgraded is big for you go head it is samsung and it is a great phone but for me its likely a no they need to do more they just add slightly better specs and think im going to keep buying every year I hope this helps
