The story so far ...
The new machine is incredibly fast, quiet, the display is terrific, gets into a ready to use state from deep sleep in < 10 seconds, and with my current heads down focus on my Windows dev work, it's a treat. The Parallels VM on a Mini was getting to be a little clunky, though I was a few versions behind.
The new 27" 4K displays are terrific, it makes the whole experience pretty stellar, I've got a ton of screen real estate, ultra crisp text, the notebook is running a VNC session to the Mini in full screen, very handy for messages, grabbing a file, accessing photos.
Windows 11 has some great features, like excellent window management, it definitely has a lot of MacOS vibe with how the taskbar is designed, some things I like better, but without getting into too much Windows 11 vs. MacOS, I'll say that the former has definitely improved.
Game performance is stellar, even though I haven't really played anything, but we have plans for this weekend
The plan is to connect (via HDMI) to the main TV and use an XBOX controller (already connected and tested), and I imagine the Sonos audio system will really shine.
