Google Nexus 4, 7 & 10

Today, Google Nexus devices were sold out in a few minutes. Are there too many buyers? Are we not capable of anticipating market demand? Or do we just like the sound of sold out?  With the internet machinery that Google has it is hard to accept if they failed to anticipate the demand. It sounds more like the decided to downplay the anticipation. Throughout world, Australia, UK, US, etc. Nexus devices were sold in over 30 minutes. I would have enjoyed the sound of “sold out” if the online market were to be open for several hours. A quick sell out is obviously a planned sell out. Hopefully I will get my device soon.
