The biggest barrier is that QubesOS is picky about the hardware. But it can be installed on a miniPC. Then one would use a Remote Desktop app to share screen and use it remotely. No more worried about laptop, battery, RAM, etc. It’s better if it runs in a VM.
I know people are quick to say it may not be secure. But how secure would it be exactly?
Traffic is generated within QubesOS. Maybe there is a RDS that doesn’t leak.

@fepitre did a fantastic job with this:
Just be warned that it hasn’t been properly tested yet on 4.2.
True, but now you’re worried about your network traffic fingerprint, latency, your ISP, edge networks monitoring you, and open ports on your Qubes machine that go straight into dom0!
And Qubes OS via VNC won’t protect your laptop from USB or clipboard attacks, either….

About as safe as if you were running a web browser as root, but much worse.
If they didn’t “leak”, then you wouldn’t get a screen picture.

One more thing, if this wasn’t done properly, it would be entirely possible to inadvertently connect to a spoofed Qubes machine and give some random your password.
I use sys-gui-vnc to use a Qubes OS system remotely over a VPN running in a dedicated qube. I explain my setup a bit here Is sys-gui-vnc working at all? - #9 by solene
I consider it to be secure enough, but it depends on the threat model as usual.
