Samsung abandoned Edge functionality basically, perhaps it's too techy. People have 10 thumbs that's why half like iPhone. iPhone hasn't really changed in 10 years except for size. Talk about a lazy customer base.
Note Edge only appealed to tech savvy people like us, a super tiny fraction of the users so it went away. Also real Edge screen is going away and Note line is geeting more consumer friendly and less pro looking even though it's $200 more. Note 7 looks just like S7 Edge. Is a pen worth 200?
