Problem they have is a bottleneck in production, people want them but can't have them due to so few being made. That only increases the hype, but it's weighted. I suspect we will see a lot of problems down the road when it's time for maintenance, the insides are extremely fragile and most people will take it upon themselves to replace wearable items only to brake other things in the process...
If you look inside these units they require a delicate hand. In a nutshell that's what I mean about get off the ground.
Mark my words, the theme will be, "they're throw away units".
