Memory is the clearest example I know of a component going from commodity to bottleneck. Here is how I have been reading it, and what would change my mind.

Thematic reports are where I write up the ideas I am actually positioned around, in plain English and with the risks attached. They are free to read, you just need an email so I can send you the next one.
