I'm one of the Plasma Mobile developer and I would be happy to answer questions.
How do you see this develop in the future, especially concerning the convergence aspect of it - the ability to hook it up to a monitor and use it as a real desktop computer. Please provide your own personal and unofficial opinion.
Now while I think the feature is cool, I'm not sure how useful it is. I don't really see myself using it and would prefer in almost all the case using my thinkpad with a good processor and plenty of RAM. This might change with future versions of the Pinephone getting more powerful with the time. For the moment, I'm happy to have the convergence of the applications with Kirigami, so that I only need to develop them once and use a similar interface on both my phone and laptop. And having KDE Connect to share stuff between my phone and my laptop.
