All of that stuff is fine and good but it's the same incremental progress as always. I don't see anything particularly special about using this device with a dock, that seems like a really niche use case. These type of devices are not new and have never been big sellers. I'd assume most customers would just use it for games and don't care that it technically runs Linux and allows them to switch out of their game and fumble around trying to use LibreOffice or GIMP on a touchscreen until they get frustrated enough to plug in a keyboard. Unless Valve is planning to invest billions of dollars in overhauling KDE for general uses (including non-gaming uses), then I don't think anything is going to change significantly. Yes, that's how much money it would cost. This is what Google had to do to with Android to make that kind of "Linux" a viable platform, it won't happen with anything else unless similar amounts are invested. And for windows software I'm not talking about Microsoft Office or Adobe, I'm talking about the "long tail" of Windows apps that don't get attention from Wine developers. There's still a lot of those.
