QUOTE: "Even listening to Intel's description of Haswell you can get a good idea for where part of the industry is headed: everyone is working towards delivering a platform/device that has the battery life and portability of a tablet, but with the performance and flexibility of a notebook PC. Apple has remained curiously quiet on this front, but I suspect that too will change in good time."
