I had a SS 6 and planned to get an identical SS 8. Main wants were: larger screen, faster charging, QWERTY keyboard. That was really all.
Thought about it a bit. There was nothing I needed on the S8 the S7 didn’t already have - so I looked at S7 refurbs on Apple.com at $550. Hmm. $550 for last years model and it would look identical to what I had. Decided to sit it out for S9!
Then I started reading Ultra posts here. Big mistake, lol. Went back and forth for a respectable time then spent another 250 for an Ultra.
Thought the size might annoy me, but it’s great. Love the different style.
