I think they are wondering if one extension can use both v2 and v3 APIs at once? As in whether v3 APIs will be “backported” to allow v2 extensions to use them

Not recommending against RustDesk - it is a very cool project - but regarding the “Why?”, you could use a VPN or something like Tailscale which has MagicDNS that’ll resolve hostnames of computers to their local IP address. You can use this with GNOME’s RDP server to remote in from another device pretty easily.

PairDrop(dot)net is a fork with a bit more features

Just use Waydroid instead: https://waydro.id, much lower overhead, however you need to mess with ARM emulation. For installing Google Apps and Device not Play certified: https://github.com/casualsnek/waydroid_script

Dell laptops have mostly just worked on Linux quite well, but you may run into issues with the camera, however this hack(?) has worked for me: https://github.com/stefanpartheym/archlinux-ipu6-webcam.

I believe Dell has a catch for the camera saying that it may use more CPU when in use. Whilst the laptop is Ubuntu Certified, the camera only works if you select the Ubuntu option instead of Windows, and use the install they give you.

Some other nice things to have:

• fwupd should also work for firmware updates, hopefully. My speakers sounded worse on Linux than Windows, some tinkering with hdataskretask helped a little, however it’s still worse.
• This should let you change some bios settings, like changing charge limits and thermal profile (cool, performance, balanced etc): https://github.com/dell/libsmbios
• This GNOME shell extension allows you to change charge limits easily: https://extensions.gnome.org/extension/5724/battery-health-charging/

re: OneNote

Although not a replacement for OneNote on Windows 10/OneNote in Microsoft 365, you can get Waydroid and run OneNote’s Android app with it.

I don’t have a stylus so I’m not able to check if everything works, but if it does, it’ll hopefully feel better than the web client, which wasn’t able to keep up with stylus strokes last time I checked. The number of pens is lacking though, even the iPadOS version is better…
