Well, as promised, we are talking foldable this week. The excitement is palpable, and it looks like the rest of our mod team have already started the conversation here. Go check it out.
I honestly don't know very much about foldable phones, so I'll let the rest of our (very smart and knowledgeable) mod team handle this one this week. :)
Last thing for future reference at the end of the week, we also have a great thread discussing foldables here too, go check it out if you want more great discussions.
I went to the Samsung™ store and fondled their latest foldable phones lineup. Even on the demo models, you could clearly see the crease. It will only get worse as you use it. I think there is a market for folding phones but as separate screens, i.e. 2 or more panels side by side. If you gonna have a crease, might as well separate the screens.
Microsoft made the surface duo some two years ago and it didn't do great (though the screen wasn't necessarily the reason for that). The problem I see with that approach is that you can't have content going all the way across due to the bezel between the screens.
