Software
Never underestimate or forget how nice the vanilla-esk Pixel rom is. I did tell my OCD that it was ok to double up on apps like samsung browser and chrome, or samsung gallery and google photos. Samsung has toned down their influence over the past few years but when you even slightly scratch the surface you can tell there is bloat and crap everywhere. Maybe not bloat, but things which just get in the way and annoy you. Take changing the wallpaer for example. The pixel has google wallpaper which is great. Samsung has a wallpaper picker at the top which takes up about 20% of the screen, then tons of themes they try and sell you for 99p. I found this all over the operating system and it really hurts the user experience for me. The biggest problem was that no matter what I tried to do, I was continually asked to perform an update.
The icing on the cake was when I started to realize that I was slowly turning it back into a Pixel (nova launcher, google apps etc etc), but it would never be the same as a pixel. Unfortunately google wallpaper crashed my s8 when I tried to apply a wallpaper. Grrrr
Final Thoughts
Ignore anything I have said over the past few days. Google can charge what they like for the Pixel 2 XL. I'm buying one. I know it will be fantastic.
