That's at least my replacement until something comparable is reached in Linux OS world.
The Volla tablet should get support on UT soon, at least I hope so and look forward to it.

The Volla Tablet is available with Ubuntu Touch working on it.
I'm currently at the Volla Community days and I will test a couple of apps if I can.

There is a lack of tablets compatible with Ubuntu Touch, but what you're saying about running desktop apps on Ubuntu Touch is changing ; with a keyboard and mouse/touchpad apps available for ARM should run on Ubuntu Touch and with the compatibility with snaps it brings a lot of apps to try out.

Of course we cannot guaranty full compatibility, but it might work...

Also the best way to have something is not just raise an issue in a forum, you can create a real issue (feature request) on Gitlab and sponsor developers or raise founds to get the feature you want.
This is a community, which means the effort is also shared across our community members.
Sitting idle is not being part of a community (and to be clear I don't say that you are, I'm just encouraging everyone to contribute)

Hi @naizena
I share your frustration, but we do not have a say on the hardware development.

I am feeling just like you. As a matter of fact, I raised this issue already 5 years ago, see https://forums.ubports.com/topic/5207/libertine-and-desktop-apps-in-ota-14/5?_=1749883727005

I don' think running desktop apps on a phone, even with an external screen, is the main interest. What would be of more interest in my mind is to be able to connect a tablet running Ubuntu Touch to a BT keyboard and mouse and use it as a desktop computer (running desktop apps). Using BT connections is no problem, but running desktop apps on Ubuntu Touch is still a problem. I wondered last year whether this had improved with Focal (see https://forums.ubports.com/topic/9953/desktop-apps-on-focal), there was NO reaction.

I am sorry to say that the only ones who succeeded in making a tablet that can also be used as a (small) desktop computer are Microsoft with their Surface Pro device.

I am continuing to check the UBTouch Forum once in a while for progress on this topic, but I lost hope...

Does anybody know of any other wireless display adapters that work well?

Mine wasn't cheap, $60 CAD (€40), but if using an external display is an important feature to you, it's a shame not to be able to. I get minor latency in display (well under 0.5 seconds), and two-finger scrolling doesn't always work when using the phone screen as a mouse. But with a Bluetooth keyboard and mouse, it's great. And while not every app is well set up for it, on the whole the OS functions very well in desktop mode.
I hope you're able to find a solution.

I found it amazing that we can do this with the Fairphone4 an already with the experimental port of the Fairphone5.
And all that with a very small team of enthusiastic developers.

As with most things in live it's neither black or white but somewhere in the middle.
Glass half full kind of thing :winking_face:

For others devices, in many cases a wireless aethercast is possible.
