I'm like 99% sure I will get it, but with little enthusiasm or excitement. This is primarily due to the lack of any significant improvements to the camera, specifically the lack of rear dual cameras and higher fps slow motion. It doesn't really feel like there's a ton of improvements outside of aesthetics, and losing the home button is a real pain point for me -- I used to wake up the phone, answer calls, and, of course, scan my fingerprint with the home button. I could wake the phone and scan in one step by pressing and holding the button, something that is no longer an option. Frankly, I hate on screen buttons, they make typing hell when you dip too low reaching for the space bar.
It's also annoying that the screen is so tall -- I'm all for adding 200 pixels to make up for the usable screen loss for on screen buttons, but 400 pixels seems excessive. Pulling down the shade with the 2:1 screen requires extreme manual gymnastics or (heaven forfend) two hands. And I pull down the shade ALL the time.
And now I have to deal with either going with the S8 and losing battery compared to my S7 Edge or sticking with the S8+ but skirting past the point of one handed use. S8 with 3500 mah battery? That would have been a no brainer.
That said, I'll still very likely buy the S8 or S8+ because of things like the 64gb internal. Because the edges are less curved than the S7 Edge. Because the thing looks so damn nice. Because the G6 and the Pixel excite me even less. And frankly, Samsung locked me in because of Samsung Pay -- no other manufacturer has MST for payment, and in the US, you won't be able to use your phone to pay with a majority of vendors without MST.
So yeah, I'll be getting the new phone. But grudgingly so.
