never used SwiftKey on my iPhones before. But wow, SwiftKey is pretty amazing with swiping words (yeah, I know...you guys probally use it allready for quit some time haha)
Still need to get used it, but quit like it so far. In my understanding, after a period of time it will predict what I am about to typ, nice!
I used to use Swiftkey up until a few months ago, loved it. But then they changed their policy and a lot of people said it was real "invasion of privacy" level type stuff, so I've stopped using it now.
It was better than GBoard (official Google Keyboard) but GBoard has caught up a lot and I'll probably stick with it for foreseeable future.
So far it seems like iMessage is one of the biggest things holding people back from switching to the S8. Google has done so well in many different areas except messaging. If RCS could ever get off the ground and be standardized then things would be much different.
I've always been on Android for my phone so maybe I don't know what I'm missing, but between using the stock Samsung messages with SMS and MMS, Facebook messenger, Skype, and KIK I don't have any issues with communication between different platforms.
With that said a single modern standard going forward would be really nice.
I understand in America it's a big deal, but the rest of the world all use WhatsApp which is cross-platform, so in reality iMessage kind of matters less and less as time goes on for many, many users.
