According to Piper Jaffray analyst Gene Munster, the Apple decision to slash prices across its MacBook lineup will soon be corroborated, given the fact that Apple appears to have hit the winning trail again with its June shipments of the Mac, following months of plunging Mac sales vis-a-vis the 2008 figures.

In a recent research note to clients, Munster noted that some configurations of the new 13" MacBook Pro supposedly have limited supplies both in the Apple retail stores as well as online. That the boost in sales of Apple's most popular laptop has surpassed expectations is a good indication, as it underscores a notably robust back-to-school buying season.

The Apple Web site shows that there is currently about a 7-10 days delay in meeting the orders of its 13-inch MacBook Pro configurations - particularly after Apple renamed the model, from its earlier name '13-inch MacBook,' at its June 8 Worldwide Developers Conference on June, where it also slashed the price of its Mac notebook lineup, bringing the price of its base 13" MacBook Pro model to $1,199.

Saying that his firm is "increasingly confident" that Apple is finding it difficult to keep its new 13-inch MacBook Pro in stock, Munster added: "We see this as a sign that demand is outpacing the company's build expectations, and it may take several weeks to reach a supply-demand equilibrium."
