I don't know about that. NExT was pretty revolutionary and it worked really, really well. If they could have gotten the hardware price down to something a college student could afford I might be typing this on a completely different stack.
Sometimes a radical shift is what's needed. Apple is the new Microsoft and might just be ripe for a disturbance.
And that's not even getting to the tricky parts like virtualization or CUDA drivers.
I have dreams about this, and think the bare os must be a kind of hypervisor.
Then, on-top, you can launch "classic" OS like windows, linux, etc. Then also, the new OS.
i've had the same thoughts. I think the future might be hyper-visors hosting operating systems of all types, each one serving a singular purpose for which is configured to serve most optimally.
I want better hardware, but as a pro software developer, I can't really adopt a fundamentally different operating system, even if it is "better."
I don't care how nice your hand-crafted kernel is; if I can't run a JVM, Node.js, and the Android toolchain on it, I can't do my professional work on it.
