Yes unless both my phone and headphone support LE Audio.

Firefox only uses wayland by default in nightly. You can enable it in stable version by setting environment variable MOZ_ENABLE_WAYLAND=1.

• GNOME removing Server Side Decoration support in wayland.
• MultiMC author rejecting people build it from source by themselves although MultiMC is under Apache license.

• X11 + Intel card, 1080p 60fps, GPU fully utilized, one third of frames dropped! 4k 60fps is about the same. It turns out that the focus is not on the resolution (the GPU isn't used to its full capacity anyway), it's on the frame rate of the video.
• Wayland + Intel cards, 4k 60fps, not even dropping frames, let alone anything else, and the GPU is used for about half of the graphics calculations.

For hardware decode, when I switched to wayland, it was only implemented in Wayland. After they implememted EGL on X11, they implemented hardware decode on X11 as well.

For mixed DPI, applications can implement it use screen information, but not all applictions will do this. But wayland ask them to implement this feature.

It's reference implementation, but isn't suitable for daily use. Because it lacks some convenient features. It's used as a behavior reference when some one develop a new compositor.

It may be related to Nvidia. Most bugs I met in Wayland is related to it. Such as no dmabuf export support, and vulkan init will fail because a bug in nvidia prime implementation...
As Linus said, so Nvidia, fuck you...

You should, I think. You don't have Nvidia GPU, so you can avoid almost bugs and get better performance.

Advantages:

1. Better performance. e.g. for Firefox, @lilydjwg got double performance in wayland.
2. Better multi-screen with multi-DPI support.
3. Better maintaince. Many DE has put more and more to wayland. And many new features will only be implemented in wayland. (That's because implementing many new features will be difficult or even impossible in X11 old software architecture, as KWin developers said.)

Disadvantages:

1. Some missing feature, such as remote desktop.
2. Many bugs when you use Nvidia GPU.
3. None of the compositors except KWin and Hyprland can use input methods with electron.

I don't know which DE/WM you use. If you use Plasma/GNOME, migration is simple, just switch in SDDM/GDM. If you use i3, you can try sway, it's compatible with i3 config. If you use others, you can try hyprland or wayfire. Wayfire has fantastic animations.

I switch to wayland because I buy a new screen with different DPI... But when I switched, I found I got better performance and video hardware acceleration in Firefox (this feature was introduced to Firefox Wayland first).

No. Just because I'm not always able to use my own device. If I use other layout and have to use other's devices (e.g. library computer), I will be confused with normal QWERTY layout.

HAM stands for amateur radio operator. That's originally pejorative usage (like "ham actor") for amateur radio operator by operators in commercial and professional radio communities.

Canokey, there are two way:

1. You can buy one Canokey Pigeon, which is close source, but with protection of security chip.
2. You can make one Canokey STM32/NRF52, which is opensource, but no security chip protection, so if someone got your key, she can extract the key from it.
