Jerry did another video for the Samsung Z flip, in response to Samsung’s response to his first video. He discovered that there is an ultra thin layer of glass, under the top plastic layer. He concluded that the feature was still poorly named, and not very useful, since even though that layer was glass, it doesn’t deliver the “glass experience” that people expect.
Well in my "glass experience," glass breaks when bent. This stuff didn't break, and on the hardness scale it was scratchable at a 3, if I recall. Glass scratches up around 5.
In any case, I'm going to wait for the "next generation." My first computer was over $2k, and the subsequent purchases were mostly around $300, yet far more powerful. If these folding phones get better and drop to $100 or so, deal me in!
PS: Kudos to Jerry and all the other angels out there who review products and freely share their experience with the rest of us!
