So the only real benefit compared to my MacBook Air is that the screen is a bit nicer, and I can keep more Firefox tabs open, because it has more RAM.
I'va been migrating my workflow to this approach and I'm an embedded dev! My closet does have hw strewn about but once you set it up that you don't have to touch wires it's super convenient.
My one gripe with MacBook airs up to m4 was support for only one external monitor. But m4 fixed this.
RDP: Every time a native notification pops up, I get disconnected (usually the notification is about something I've been doing, such as starting a self-hosted server or running winget via unigetui). It randomly disconnects when I've been using it for more than a few minutes, even when there isn't a notification. All of this so far seems to be limited to Android's rdp client (the Windows app). For Windows built-in RDP client, my issue is that there's no way to make it resize the desktop like vmconnect does when you resize the window (and no way to proxy vmconnect connections easily for home use--I do not want to enable WinRM for the full system and figure out how to secure it, I just want a single PC on the LAN to be able to access a single VM conveniently, preferably able to log in as different users)
But there's issues with ssh (and likely WinRM/ps remoting, though I haven't used it) as well: with Linux you need to use sudo, but with Windows there's apparently no CLI requirement; ssh runs elevated (though apparently you can change this; I make do with connecting to a running psmux session that's not elevated). So far as I know, there's no way to elevate without the GUI being involved (admittedly I haven't looked since I started using ssh with Windows).
Linux? Connecting to Linux works perfectly. I can't use xrdp or ssh or vnc or forwarding x11 over ssh or [other] and they work perfectly. I used to use x2go before Wayland, and despite the pain of actually getting it working even that worked better; XDMCP required some amount of setup, but it was awesome (too bad there's nothing that efficient with Wayland); xpra looks great, but either didn't exist or I was unaware at the time. The only issues with Linux remoting are, again, Windows-related (it's seemingly impossible to get vmconnect enhanced session to work properly with Linux at all on Fedora 43; the things I've found online don't seem to work for me).
