I'm incredibly interested in COSMIC DE! For multiple different reasons, actually.

1. Rust - I'm very interested to see how performant/memory-efficient this DE will be compared with other DEs. Also, I wonder how the Iced toolkit will evolve and be adopted in other projects.
2. Benefits over GNOME - I'm looking forward to seeing how much out-of-box customizability and features come with COSMIC over GNOME (which I'm currently using).
3. Maintainability going forward - Since the DE basically started from scratch and is using a much better language for robust software, I wonder how much easier and faster it would be to maintain the desktop environment. This potential improved maintainability could be huge in overtaking other DEs sometime soon.

I'm really looking forward to it.

On the technical side, they are using pure Rust to build the DE, and the Rust GUI ecosystem has been greatly improved. If their product turns out to be successful, Iced may eventually become "the Qt of Rust".

As a user I like their design shown in current demos, and a wayland-first DE with first class nvidia support is really needed.

I welcome new and innovative DEs. I am tired of how some organizations handle things. I must however, acknowledge that with every additional major DE comes further fragmentation. COSMIC seems to really care and for that reason I am rooting for them. The negative effects, however, are always in the back of my mind.

At first I was excited, not because of the desktop environment itself, but rather because of the headache pain points in gnome and KDE that it sought to fix. Things like fractional scaling and native HDR support as well as being built around Wayland all played to cosmics benefit. Unfortunately for cosmic, however, KDE has really improved quite drastically this past year and fixed pretty much every pain point I had with it. They seem to be shaping up to blow cosmic out of the water before it even arrives with plasma six. Gnome is doing gnome and by that I mean they fucked off and are doing their own stupid thing. I hope cosmic does well, but it would have to be the third coming of Jesus Christ to get me to switch again

A couple of months ago our company decided to standardise on only one GNU/Linux distro and they chose PopOS. While the default desktop is better then stocj GNOME it was still far away to what I am used from the powerful, featureful and customizable KDE Plasma so after about two weeks I switched to KDE Plasma (unfortunately they have an extremely old version in their repos, but still much better).

I can only guess that Cosmic will be on pair to their current improved GNOME but will still be way lacking compared to what even an old KDE Plasma offers. And I would also much more like to see if they put more attention to keeping more updated KDE Plasma and KDE software packages in their repo. Even for Cosmic I think they would be much better of basing it on the extremely flexible and configurable KDE Plasma base and make it a heavy modification of this.

Personally, I would have preferred if they would have embraced KDE instead and dedicated resources to improve KDE even further. KDE is pretty darn good already, especially over the last year or so with all the bugfixes and feature improvements.

In any case I am happy System76 is moving away from Gnome at least, and coming up with a full-featured DE of their own rather than having to maintain hacky extensions on top of Gnome to make it usable. As a bonus, the Iced toolkit should see improvements and perhaps become the goto toolkit for Rust GUI development.

I feel mixed. The shift towards COSMIC DE got me off of POP_OS. I wanted the newer Gnome features, and that stopped being their focus. I don't wanna wait 2-3 years for a great DE when I already know I like Gnome. I switched to Fedora and use Pop Shell, and am really happy with my OS now. I also felt like the public shade between Gnome devs and S76 devs was tacky. With that said, I bet Cosmic is going to be great eventually. It'll be great to have DE in the ecosystem with a focus on performance, UI, customizability, and actually looking good. Even if I don't use it, I bet it'll push the other big DEs to get better. Friendly competition is good. Also, it's ridiculous that you have to go with a WM to get tiling, and that it's not easier to get in Gnome. Real glad Pop Shell is still available, but I don't think anyone's maintaining it so it can't last.

System76 is doing huge leaps for Linux as a whole. They already offer the best bios on the market. I am keenly looking to buy their upcoming Virgo laptop when it's ready.

I'm excited for Cosmic, but not because I'm interested in trying it, rather that I want see how their toolkit does. They've done a good job on their Gnome fork so I trust they know what a good desktop looks like.

I really want to see Iced in action because of how it could compare to the current state of GTK.

It has been a little over 2 years since GTK 4 released to positive reception and no one else has ported to GTK 4 yet. Even worse, only Pantheon is actually working on a port, and the other GTK-based DEs, XFCE included, don't have plans to port to GTK 4 yet. Given the lacking pace of this transition and System76's decision to forego a port at all, instead developing their own solution, makes me worried that GTK 4 is either much more difficult to port to than Gnome let on, or that GTK 4 has broken something so essential to these DEs that they don't want to put development time into a port at all.

Given this state, I'm curious to see how this plays out because it could decide if other DEs stick with GTK or choose to adopt something else, like how LXDE was discontinued in favor of replacing it with LXQt.

Edit: Fixed a couple typos

Skeptical. Writing a graphical UI toolkit is a freight train of work. I'm positively curious about anything that's not GTK but I'm not sure going with a new toolkit is the right decision. Qt is the mature kid on the block that's been proven in more environments than I can count. Moreover it's a complete application framework with a ton of convenience libraries needed for speedy development already included. I guess those can be supplanted in the form of separate Rust libs. Personally I'd have gone with Qt for such a project but I'd be happy to be proven wrong.

I think it has potential, and more choice isn't a bad thing. It will be interesting to see how it goes up against the more established DE's once is has launched.

Always happy with more choice as it's one of the main things that brought me to Linux many moons ago. Don't like the way your DE does things? Well then swap it out, wholesale or otherwise. Personally, Gnome aligns very well with the way I like to use my computers but I also love to see what the KDE devs are doing with Plasma so I'm always interested in seeing another fresh take. My only real concern is that a whole DE is a heck of a lot of work and requires significant resources that will get stretched thinner and thinner with each new feature and option and I'd say they'd need a fair amount of community buy-in to keep up with it all long term in an ever changing PC market.

I'm a big gnome fan. It's been my DE for years back with v2. System76 have done a lot of hard work and I welcome more competition in the desktop space but I'm sticking with gnome.

I'm really in support of everything that System76 is doing. Outside of Framework I think they're one of the more interesting enthusiast projects. I think what makes me particularly excited for Cosmic is that it will be under the GPL3 license, and that it will use GTK.

I'm excited to see it, not to use it. I'm much happier with GNOME or Sway on Fedora. Unless they provide a way to use it on other distros (which I don't see happening, since they have no reason to), I don't plan on trying it. However, I am excited to see the Rust GUI situation improve by them using it!

The only reason I use GNOME at all is the Pop Shell GNOME extension. They're building that functionality into COSMIC, which is great. Long as the project doesn't wither on the vine, I'm looking forward to taking it for a spin.

I love the looks so far, and all of their ideas with it appeal to me. I used Plasma for a while for its customization, but felt that even the best tiling extensions were lacking. If COSMIC follows through on the tiling features, it'll be a no-brainer for me.

Super excited for it! System76 does a lot of amazing work for the community, and I love what they’ve shown so far. I daily drive Pop OS on a pang12 system76 laptop with a Launch keyboard (bit of a fanboy haha)

I switched to tiling window managers a good 5 or so years ago and really can't imagine using any of the DE available. I know, I know, you can run xwm in yDE, but I've never seen the point.

Rust is badass, GNOME is currently led by a group whose main activity has been to try to ruin the project as much as possible, and more desktop environments are always welcome in my book.

It looks interesting and I’m excited to give it a spin

Totally supportive. Great to have a wayland Rust implementation (and Rust increasing adoption by FOSS community); more specifically, smithay, which further than System76 is building upon, like projects by the community this WM for example https://github.com/MagmaWM/MagmaWM

Just a clarification - it is based on GTK, right?
