MacBook Air-radical redesign for its Mac Pro

 Apple introduced a much-needed and 
radical redesign for its Mac Pro
desktop line this week, but its
 refreshing of the MacBook Air
 was all internal – the laptop’s look has not changed since its revamp in 2010.

Since then, many Windows laptops have tried to copy the Air’s classic wafer-thin looks and it has inspired an entire “Ultrabook” category, created by Intel.
