On that note, though, I don't see this as being a 'game changer' - more of a marketing gimmick if anything, and an unnecessary addition to manufacturing costs. Samsung tried to find a way for one of their units to stand out from the crowd of identical-looking smartphones, and this is the result we were given. I suppose it worked with all the press they seem to be getting around here.
I dunno about it being a game changer, but it's not a marketing gimmick. The edge display fills a real need. Phablets are extremely popular in Asia among women. They slap a case on it and carry it around in their purses.
Unfortunately if they get a text, that means they have to pull the phone out of their purse and flip open the case to read it. Find out it's not an important text, close the case, and put the phone back in their purse. That's a lot of two-handed maneuvering just to find out it was an unimportant text.
The cases with a cutout window in the front (which kinda defeats the purpose of a protective case) were the first attempt at solving this problem. It eliminated the step of flipping open the case to read the text. But they still have to pull the phone out of their purse, and put it back in.
The edge display solves this problem entirely. Woman gets a text, opens purse, peeks at beginning of the text on the edge display while the phone is still in the purse, decides it's not important and closes purse. No need to pull out the phone.
