This is so true. In a controlled environment I’m sure it will be fine but where I felt the burden of the note 10+ (and to some extent my current OP7 pro) is using it on the move.
I pre-ordered the plus this afternoon. Can still change my mind or even cancel completely but the plus feels like the best one for me. I will watch camera reviews with interest though, couldn’t care less about the 100x but if the overall camera is significantly better on the ultra I may re-evaluate! There is still a chance you know that the pixel binning won’t work as well we hope and that the 20/20+ could actually be the better general camera!
Size-wise, whether you get the regular S20 or the S20 Plus, I think you made the right choice avoiding the Ultra. I know everyone is different with their preferences and that it's largely subjective, but for most of us using something like the Ultra will be a burden unless you, for some reason, prefer to use two hands on your phone a lot of the time.
If you want to know whether or not you made the right choice size-wise, just go to any Best Buy or carrier shop and hold and S10 Plus. The overall volume of the S20 Plus is almost identical to that of the S10 Plus. In fact, despite being slightly taller, the overall cubic volume of the S20 Plus is ever so slightly smaller than the S10 Plus. Basically, those two phones will feel identical in the hand.
