I kind of prefer the form factor and size of the the S9, given bigger displays on smaller devices now that they've gone bezel-less. But it really sucks that we'd be sacrificing 2 GB of RAM vs. the larger S9+ if rumors are true.
I had the S8 Plus then downsized to the regular S9 last year. It still felt like a big phone because like you say thanks to no/little bezels you get way much more screen in a smaller form factor. I missed the bigger battery of the Plus but that was all. I'd probably be looking at the regular S9 this year too but the fact it won't have the dual cameras is a deal breaker for me personally. The smaller ram is just the icing on the cake
I really hope there's more than 64gb of memory. I mean, allow me to save private files to my sd card or give me more memory! And I really hope the FPS isn't on the back. I really like being able to unlock my phone when it's on my desk without having to pick it up. Small things I'm sure I'd get used to if they didn't have it, but I'd really like it. LOL
