Following Wednesday’s media preview event, Apple’s massive new retail store in Manhattan’s Grand Central Terminal opened to the public today at 10:00 AM. As noted by Fortune, the main concourse of the terminal was filled with hundreds of people waiting for the store to open as hundreds more red-shirted Apple employees prepared to welcome them.

As is traditional for Apple retail store openings, the company is handing out store-specific T-shirts to early visitors. Fortune notes that Apple has prepared to hand out 4,000 T-shirts for today’s opening.
