Yeah, they totally knew what they were doing. Hence the smooth scaling up to filling the demand for 100,000 on the first day. I remember my personal smooth shopping experience.
Yeah, I wonder how much customers they lost because of the supply problems.
I was very existed on the day it started selling (or DDOS those two sites), wanted to buy two. But I wasn't able to, so I waited few weeks until I could place an order, but my interest faded with time, and as of now (almost year after they started selling it) I still don't own zero respberrypis.
