I'd really enjoy developing on this platform, but $3,500 is too much considering there's a real risk that the product doesn't stick.
I think any team that can just buy 10-20 of these to build with is too comfortable to make anything high quality, they're experimenting and return is a bonus, not a requirement. There is no entry point for individuals who expect some return. Apple should have shipped something for developers that isn't $3,500.
I hope it does stick. I think that this tech will be amazing after some iteration, I like their choice of external battery, and their ecosystem has always been top notch.
