I’ve been following Qubes since Snowden mentioned it. I didn’t want to use Qubes until 4.1 and used that time to carefully pick the hardware. Waited for stable QWT as well. Then I started to use it form the early 4.1 betas. Always updated it regularly and I still use that first installment.
Never, ever, not a single time it crashed. Never, ever, not a single time froze. Fully functional sys-audio even with Windows qubes, fully functional Windows dispxxx qubes, apt-cacher-ng, customized disposables for services and in general, and now preparing to transfer to sys-gui-gpu, even infamous xHCI USB controller now in HVM mode. And, me being a noob, the one could imagine how bloated or compromised it could become from then till today and still stable as a rock.
So, being inexperienced the only way I can interpret
is that the chosen hardware isn’t good enough for security standards set by Qubes. Or, some misconfigurations, more probably. Whatever, I’d wanted to share that there are some of us extremely satisfied with 4.1
