I'm really hopeful a 15" is not too distant (but seems like it might be). I have an aging Dell XPS 9550, but there's not been much I've wanted to jump at. I looked briefly at the System76 Kudu - are there any go-to 15" Linux-friendly workstations?
It seems a lot of developer-type folks have moved to cloud focused work, at least in my bubble the raw computing power seems to be less and less valued.
