This is the only bit I read, the rest was blah blah. The first entirely predictable delay of many, if I might add. They are on a long road to "Sorry we tried, here are some discount coupons for purism laptops". Well, it won't be that long really, unless a badly needed funding angel swoops in.
Their delusion is in some sense laudable, as any startup should believe it's own bullshit. But when you know better than they do about their chances, it's still hard to watch folks put themselves through this.
