Many Apple Stores are not carrying the new MacBook yet, some models don’t ship for 3-4 weeks

Joe Rossignol, MacRumors:

A spot check of several Apple Stores in the United States, Canada and United Kingdom resulted in us being given the same response about Retina MacBook stock being unavailable at each location, at least on launch day...

Retina MacBook shipping times also slipped especially quick out of the gate, with custom configured models available to ship in 3-4 weeks from the moment orders became available, and gold stock models following shortly thereafter.
