What's so impressive about this thing? Is the S-pen as good as Apple Pencil? Can I sketch with it? Can it keep up with my handwriting? If not it's not going to be that useful. And the software Samsung has always had to support it has been half baked, slow, and inconsistent.
If I were to get a Samsung phone it would be the S10e, that's the limit on what I'm willing to spend for a Samsung or even an Android phone, and even then I'd be making compromises with Android.
Hardware on modern phones is generally very good across the board and the designs have all stagnated at a similar look. Hardware will never be a reason why I switch from iPhone to Samsung or anything else.
The SPen is brilliant and the best part is that it charges in its silo, no need for awkward placement, it’s also great for sketching and a lot of other stuff when multitasking.
The SPEn functions have long been advanced, since the Note 2, Samsung have just improved them with each iteration.
