CNET - Part of Apple's keynote address at WWDC this morning was a demonstration of its new MacBook Air and MacBook Pro systems, which have not only done away with optical drives but have also streamlined other I/O offerings. In order to save space in its systems, Apple has combined USB 2.0 and 3.0 connections, but has also fallen to relying on its Thunderbolt connections to provide the I/O connectivity from older Mac systems.
