I'm not sure how people keep missing the original point. Which was: the market won't choose a bunch of wimpy cpus when it can get faster ones. It wasn't about the physics (which I'm not arguing with), it was about a choice between lots of wimpy cpus and a smaller number of fast cpus. The market wants the latter, as Ted said, Sun bet heavily on the former and is no more. If you want to bet on what Sun did, feel free, but do so knowing that people have tried to tell you that is a failed approach.
