And that will be true about the Apple Vision too, how do you get there if you don’t have the ability to put the operating system and the hardware together and then iterate, the biggest problems with the Apple Vision is that it needs to be three or four times faster performance wise than what it is, needs to be half the size and it definitely needs to be more energy efficient from a battery standpoint and last but not least half the current price how does that happen? Only through iteration over time.
