I was skeptical of Magic Leap too, but their SDK is very real. Maybe seeing it in action might dispel some of the concerns.
The Apple Newton had a really nice software stack too.

Do we know what the likely price of the consumer models are? I can easily imagine dev kits staying around $2000 for a while, but that might be different to the consumer versions.
i.e. If you imagine writing an SDK for a bag of hot air, it seems like it would turn out very different from what you see there.
It's also small and tasteful. That caught me too. I didn't expect a big company to put out something elegant, but they seem to know what they're doing.
You're right though -- it all comes down to the hardware. We'll found out later this year.
