Some of these are subjective opinions, so I'll add my reasoning to why these are not valid trade offs for me:
-Glass is to enable wireless charging plus, it provides a more premium/luxurious look and feel to the device.
(I don't use or care for wireless charging, so glass offers me no benefit. It may look and feel more premium, but is kind of a pointless reason when it's more easily damaged and everyone just throws a case on it that hides said look and feel.)
-OLED screens are more battery efficient and look better than LCD. So, don't know what you are getting at there.
(Efficiency is dependent on what's being displayed, and there's some cases where an AMOLED screen may consume more power than LCD. I've seen the V40 being advertised as simply an OLED, which I've read is even less efficient than AMOLED. How they look are subjective and have more to do with how a manufacturer calibrates the screen rather than the technology itself. For example, LCD's are still the most common displays photographers use when editing their photos. Personally I haven't liked the way AMOLED phone screens have looked. I will concede they have better blacks for obvious reasons, but they also suffer from burn in. That is not a trade-off I'm willing to make)
-the notch actually isn't the big deal that it's made out to be. For example when watching videos and playing games, the notch is out of the way since it's in a section of the aspect ratio where videos and most games cut off well before.
(So what exactly goes in the screen area on the sides of the notch? Unless I'm mistaken, isn't it used for notifications and such? If so, then you get less space for that purpose. Not to mention I despise the trend towards zero bezels, which leads to a lot of false touches. Give me something to grip the phone with! Plus I just prefer the symmetry of a regular, notch free, display.
-secondary display is replaced by the floating bar which is just as good.
(I'm withhold final judgement, but for now I do enjoy the secondary screen implementation)
-Oreo provides far more functionality than nougat.
(Of all the new features I've seen, I can't think of one that interests me. All it'll do is put more of a drain on resources to my existing V20. I'm not opposed to getting a new phone with it pre-installed, but I have no reason to update my phone to it.)
