I admire your optimism, but almost every Steam Deck review complained about the UI. All the work under the hood looks really good, with Proton and pressure-vessel and so on, but they just don't seem to have the almighty yet tasteful UI dictator that a desktop distro needs. Unfortunately, that is also the part that the community cannot help with.

Still, can't wait to get mine and play around with the desktop. Ironically, I was planning to use mine for contributing to elementary, after having been locked out for a while (ARM Mac).
