I've kicked this around a lot the last few days. IMO, it shows the value of a purposely designed piece of hardware. My Fractal (insert whatever brand you prefer) for example. It is uniquely hardened for the demands of everything from studio work, to live shows. No, it can't run Windows. But I don't need it, or want it to. The internal software, and hardware components are assembled, and tuned specifically to create guitar and bass sounds that are good, reliable, and repeatable. Now if I imagine that the Windows pedal has similar physical hardening, that's a step in the right direction. However, you're still throwing a certain amount of overhead at managing the OS, and components that DON'T contribute to the desired result. I'm certain Fractal has this overhead as well, but it's been specifically designed (I realize this is my assumption) to minimize that overhead.
Don't get me wrong, I'm VERY interested in NAM technology and how good the sound is. And I can see a day when I will put up with the extra overhead. But I think a MacBook + low latency interface + bluetooth pedal is closer to what I would use. And yes, that CAN BE much more expensive. But the additional cost is worth it to me. Again, personal opinion.
