Yes, I miss the 8 size and weight; the 11Pro is great, battery, camera, night mode... but it doesn´t feel great on hands, I got used to, but is not good as the 8 was.
I'm definitely size/weight sensitive. My screen broke on my 8, so while I was waiting on the replacement screen to be shipped I went back to my 7 as my main phone. I couldn't believe how much better it felt that the 8 (in the same exact case). Now the 8 is only 10 grams heavier than the 7, the X is 26 grams heavier than the 8 while the 11Pro is now 40 grams heavier than the 8. I'm really excited to see what the 5.4" (and even the upcoming 4.7") comes in at both in size/volume and weight.
