Absolutely! The nascent state of ARM outside of iOS, Android, and now MacOS is definitely a roadblock for bringing it to projects from smaller companies like you folks.

In my eyes (uneducated, consumer-level perspective) X86 is a huge question-mark for HMD devices like this, since the heat and power usage are so counter-intuitive for small form factors -- and mitigating those concerns usually actively works against the "higher-performance" nature of the chips. (low-tdp allowances, throttling, etc.)

Like I mentioned above, I really do wish y'all the best of luck with it. I just don't envy having to be reliant on an old and power-hungry architecture just because the newer, better architectures don't lend themselves to this sort of project yet. I hope the Simula One sticks the balance!
