We can ignore the Vappies if we want to. Premies are much more insidious. With a Preemie, the vendor announces specific product availability long before it is stable and ready to deliver. Every announcement has some blurb from an industry analyst or customer that is crafted to create an illusion the product is stable and usable. You have to be very careful about separating reality from smoke.
Availability is announced to be three or more months in the future.
I have to tell you, from my experience rolling out lots of products, you can be three months away for many months or even years. Three months or more is what you say when you are guessing. But announced availability less than three months does not guarantee it is not a Preemie. The reason the sales force is surprised is because there is no way to create training materials because the product isn't fully formed yet. In the networking world, Preemies are becoming more and more prevalent, almost the norm.
