The size of the premium headset market is a big question mark, but we know Apple's conservative order for 2024 is 300-400k units and they are planning an inconvenient sales process to slow demand.
Linux is around 1% of desktop market share so perhaps 1% of that 400k would want a premium Linux headset: 4k for Simula to serve. Then we'll find out if headsets grow as a market or they fade out like a fad or transition product category.
There's no way 280M laptops are being sold in US every year. Where did you get that data?
I worked like this for more than 12 hours yesterday, too.
I strongly considered their product and found it very tempting. Not a perfect fit for me, so I didn't go for it in the end, but you have to realize the world is not full of a bunch of clones of you.
