Re: Is this a joke? It must be a joke...
Watch the presentation (about 1:22 in) because it is quite interesting. Flexible displays are hard™ and a lot of the technologies and materials that we hoped could be used have failed to deliver. Yes, it's important to see what is actually available and at what cost but mass production is due to start over the "next few months".
Personally, I think the technology could really be revolutionary but as to whether it will be Samsung that makes the most of it, well, that's another question, because I'm sure we will see a slew of interesting but ultimately useless designs.
The presentations, however, are worth watching. While "One UI" looks like an admission that Samsung fucked up UX for years, it also shows that they've finally started thinking about the users. Basically the biggest indication so far that Samsung has a coherent strategy for breaking out of the consumer electronics follower segment.
