Not sure if it’s right, but it seems to me this is really just a bunch of preconfigured fedora instances for specific use cases with containerized packages you can mix and match to your needs. Then they slap on a bunch of buzz words to make it sound novel.
The OLED seems to be more of a power consumption upgrade. The resolution is the same. Sure you will get more color depth with the OLED but it probably isn’t worth the upgrade if you already have a deck. If they offer the new screen as an after market upgrade that may be worth it. But I’m the meantime the deck HD has a higher resolution.
