After more than three years, the MacBook finally gets a new model number! A1342.
Unfortunately, Apple only allows those with 20/20 vision to find out their model and serial number. That text is incredibly tiny and difficult to read.
This new MacBook weighs in at 4.7 lbs. That's .3 lbs less than the old plastic MacBook, but .2 lbs more than the 13" Unibody MacBook Pro.
