They seem to have done an excellent job of getting the word out about this new product. I think that it will be the "new Arduino" but the current problem is actually buying them. I've signed up to be notified when more are available but you have to be quick and lucky as they sell out in minutes.
This is not really a bad thing. It means they have something people want and at $4 the price is right. In a month they will be generally available in quantity with Amazon-prime 2-day shipping. In the meantime, there is a ton of documentation to download and read.
