Honestly Graphene on desktop is best case scenario for me. Windows has too many ads and spying, Linux doesn't have enough support, MacOS hardware is too damn expensive and tightly-controlled.
Nothing feels cooler than plugging in my phone with Dex to a small USB c hub at work to get desktop mode on a secondary monitor and then using a VPN home and opening my virtual machine for a full desktop
DeX is pretty cool. Google should have gone that route from the beginning instead of that split strategy with ChromeOS. More Android apps would support big screens were it not for ChromeBooks running a different, web based OS.
Does that mean desktop mode will be available by default? Some of the earlier reporting said it was hidden behind flags and may never see general release.
