The Apple Online Store is currently unavailable for customers to purchase products, in an expected development a few hours before the company's "Spring Forward" press event is held today.
Apple typically closes its online store just before a big press event, re-opening the doors just after the event closes, and normally with some new hardware to purchase. Many are expecting that there will be pre-order pages set up for the upcoming Apple Watch after today's event. It's also possible that Apple could pull the trigger on some other products such as new MacBook models.
We should learn a lot more about the Apple Watch from the "Spring Forward" event in San Francisco. Our iMore team will be at the event when it begins at 10 am PT (1 pm ET) and you can check out our live stream from Yerba Buena for all the information and expert commentary you need.
