The section about Apple is quite wrong. Their products were held back by semiconductor technology as far back as I can remember. Some examples were never getting a laptop running with a G5 and for sure with the early phone and tablet prototypes they wanted to focus on effciency in a small package. Buying PA-Semi was integral to their product roadmap. The stuff about twitter I am not sure. You certainly do not need kernel expertise or to use the JVM at all to build a similar product these days. It seems they could be just held back by legacy technology choices that don’t really benefit the product and which competitors probably won’t need the cost of supporting. Companies should always be evaluating how critical their in house technology is to thier business and/or future product roadmap.
