There are some binary-blob software I use - production software and the sorts.
But being real about that, there’s loads of software I’ll still need that are Windows-only and thus it just means I’ll have to have a second computer on the side for things like gaming and production software. Those kinds of things just don’t really have a lot of Linux support.
In the end it’s undeniable that having ONLY a Purism system wouldn’t be viable. Have way too much stuff that Windows and Intel64/AMD64 is required for, or even if they do exist for Linux they’re not open-source and I wouldn’t want to introduce them to my Purism system because that goes against the entire point of having bought the Purism system to begin with. The reality is that relatively few things would work on Qubes + ARM64 and are open-source.
Heck even if I left gaming and making videos / music (which I never intend to do), I’d still need Windows just to sync music to my phone.
I would intend for the Purism system to just be for browsing and communication and such, and I figure ARM would be fine for that. When talking about Purism with friends I usually tell them they’d want to have another computer available to them as well, I wouldn’t suggest it to be your only computer.
That being said, long as you have another system to put all your toys on, Purism is a good system to have and I think that as long as most Linux distros and Linux software work on it, it should be fine. Then we wouldn’t have to talk about the Intel ME or anything anymore either.
I think ARM would be a pretty good cure-all for the issue of Intel ME and so forth. Then the crew at Purism won’t have to piss with it anymore and they’ll be able to focus on what’s next. Besides, a chip that comes without any of the nonsense to begin with, without any of foundation necessary for it to exist on, is surely better and safer than one you’d need to clean.
