I actually pre-ordered the regular S8 and I just got back from Best Buy and boy did I get the wrong one! I an canceling that pre-order and getting the S8+. Initially I thought the S8+ would be way too tall, but it feels great in the hand, not awkward at all. Fingerprint placement does not bother me in the least, seeing I use SmartLock with my paired watch.
I did the exact same thing. I had to double check and make sure I didn't post this and forget.
I like small phones, too, and own an iPhone SE I used to use in the summer to keep on me when I'm out biking or hiking and don't want a big phone clunking around in my pocket. But I have a Gear S2 with number sync and its own sim now so that's not as big a concern anymore to have a small pocket phone.
Once you go bigger than an SE and you're a woman my size, no phone is really going to fit comfortably in the pockets anyway. A big draw for me was the display and the one on the Plus made me want to dive in and go swimming. I'm so going to enjoy movies on this when I'm traveling.
I use VR quite a bit so I was a little concerned at the lower ppi on the S8+ but from what I could tell sticking the nearby Gear VR up to both phones as well as I could, the difference isn't that noticeable.
They are both beautiful phones and I think the smaller one might be prettier and look more well proportioned, but when that display is on, the Plus is the one I want to grab. I placed my order for it as soon as I could and now am going to cancel the one for the smaller phone in a couple of days. I will give myself a little more time for a last minute change of heart. But I can't imagine it happening.
