All of the new MacBook Pros are listed as in stock, and come with free shipping. Monday's upgrade was done silently by Apple, as the company didn't even list the updated notebooks as being "new" to the store. As of Monday morning, the iPhone 4S was still listed as Apple's newest product.
AppleInsider first reported in September that Apple was set to surprise with a late 2011 MacBook Pro refresh. The relatively minor upgrades are expected to allow the professional line of notebooks to remain competitive until Intel's next-generation Ivy Bridge chips launch in the Spring of 2012.
