There's rumors of a shakeup going around in Apple's laptop lines. AppleInsider claims, according to "people familiar with Apple's roadmap" (cute -- it's Friday, so we'll let that through), that Apple is aiming to completely revamp its notebook lines sometime this year, basically making the MacBook Air's style the standard. MacBook Pros would essentially be discontinued as we know them, and instead, the MacBook Pro would take on the Air format: Super thin, no optical drives, centered almost completely around digital distribution and portability. This is a story we've heard before.
