Wow, simply amazing! I didn’t about such great community project. Will keep my eye on it from now.
Steam Deck has better software support than ROG Ally. Also, the latter only sports standard analogs, and SD offers two trackpads (which are great, btw).
On the other hand, ROG has more raw power and a better display. I don’t know anything meaningful about the rest you mentioned.
As for the OS, Linux seems better suited for these kinds of devices. Proton runs almost anything and offers a great experience, and on top off that, you can still use it as a daily PC with the use of peripherals. But I’m probably somewhat biased, as I know and love my SD.
I know, right?
I’m currently using both browsers, and I've been with FF for a very long time. But the things that come with Vivaldi from the very beginning make it my daily driver.
From this band, I get more and more in love with Vivaldi, especially their Workspaces feature.
Interesting. What works for me is an install from Heroic, adding exe to Steam, and also a flag --skip-launcher for it. AFAIK .NET is only needed for the launcher.
